                                                                                                The Windows 10 Download Page defaults to the Windows 10 Media Creation Tool when ran on a Windows PC and reverts to Direct Download Links when ran on Linux. The Workstation Editions aren't covered in the Media Creation Tool. To get the Direct Download Links on a Windows PC, one can either switch their browser to mobile view or use the Windows ISO Download Tool which offers all Versions of Windows 10.

                                                                                                • Windows 10 Download Page (Version 2004)

                                                                                                Windows 10 Download Page

                                                                                                The Windows 10 Download Page has the following form on a Windows 7/8.x/10 PC and defaults to the Windows 10 Media Creation Tool.

                                                                                                On a non-Windows 10 PC it will have the following form and defaults to direct download links.

                                                                                                The Windows 10 Media Creation Tool downloads a series of setup files on your computer, checks the integrity of the downloaded files and creates an ISO from them. This ISO has a unique checksum as it has a unique time of creation. It has an install.esd smaller than 4 GB.

                                                                                                The direct download links are of ISOs created by Microsoft and you should ensure that the checksum matches the checksum provided on their download page. These ISOs have slightly more Windows 10 editions however these are for Workstations and less commonly used for Home PCs. As a consequence they have an install.wim that exceeds 4 GB. 4 GB is the upper limit for FAT32 and as a result some additional steps need to be carried out to make installation media that passes Secure Boot.

                                                                                                Using the Media Creation Tool

                                                                                                It will download Windows 10 setup files, check the integrity of the files it downloaded and then create a ISO from the installation files. Note because the ISO is created on your computer at a unique time/date it is a unique ISO and has a unique ISO checksum.

                                                                                                The Active Development Channel is an untested new build of Windows 10. The Active Development Channel Windows 10 builds will contain new features and as a result Microsoft now refer to new builds as feature updates. The Active Development channel has a new feature update released approximately every 2 weeks. As it is untested, there may be some generic problems and some hardware specific problems resulting in possible boot issues in some cases.

                                                                                                Not all experimental features of the Active Development Channel are popular or stable. The features that are deemed both popular and stable are then passed onto the Beta Channel for extended testing. Beta Channel users will therefore obtain feature updates less often. However cumulative updates and security patches will be issued to increase the quality of the features and overall Windows 10 stability. These updates are hence referred to as quality updates.

                                                                                                Approximately every 6 months, Microsoft creates a new Windows 10 Mainstream Channel Build. The Release Preview Channel tests this Build normally 1-2 months in advance and Microsoft issue quality updates to increase the overall quality, security and stability of the build. When Microsoft are satisfied with the overall quality, updates are released to the mainstream.

                                                                                                For more information about the three Insider Channels see:

Note that the Mainstream builds don't expire whereas the Windows Insider Preview builds only remain activated within a time window. In most cases it is not recommended to remain on an older build however for those running really old computers, Version 1709 is the last build that will run on their computer due to elevated system requirements introduced in later versions.

                                                                                                If you have came here looking for an older build as your Windows 10 recently installed an update and can no longer boot try to use the Advanced Boot Options settings to uninstall the Feature Update or Quality Update before attempting a complete OS clean install:

                                                                                                If your computer was manufactured in 2014 or later and has never had Windows 7 installed on it. You will have a UEFI BIOS and should proceed directly to Creating a UEFI Bootable USB.

                                                                                                You may or may not have these technologies depending on the age of your system.

                                                                                                If using your Computer to Download Windows and make the Bootable USB, do not change the UEFI BIOS Settings until you have created the Bootable USB.

                                                                                                It is recommended to update the UEFI BIOS before clean installing Windows 10. This can be done using a USB Flash Drive in newer models or a FreeDOS Bootable USB in older models.

                                                                                                Dell UEFI BIOS

                                                                                                • OptiPlex 390/790 – 2011 (2nd generation Sandy Bridge) UEFI BIOS – No Secure Boot, there is no option for Legacy ROMs as these are always Enabled
                                                                                                • OptiPlex 3010/7010 – 2012 (3rd generation Ivy Bridge) UEFI BIOS with Secure Boot (only with the latest UEFI BIOS Update)
                                                                                                • OptiPlex 7020 – 2014 (4th generation Intel Haswell) UEFI BIOS with Secure Boot
                                                                                                • OptiPlex 7040 – 2015 (6th generation Intel Skylake) UEFI BIOS with Secure Boot

                                                                                                On a Dell system press [F12] when powering to enter the Boot Menu. Other OEMs may use different usually function key combinations and have slightly different BIOS General User Interfaces.

                                                                                                Look for the term "Boot Mode" or "UEFI".

                                                                                                If these terms are not present on the Boot Menu you have a Legacy only BIOS.

                                                                                                Next look for the Secure Boot status (a handful of early UEFI systems don't have Secure Boot) such as the OptiPlex 790 boot menu below. These system will use a UEFI Boot that always enables Legacy ROMs:

                                                                                                In the UEFI Boot Menu above some systems will allow you to select Change Boot Mode Settings to UEFI without Secure Boot or Legacy Directly:

                                                                                                Windows 10 64 Bit should be installed using a UEFI Boot with Secure Boot (when supported by the hardware). A Windows 10 32 Bit install requires a Legacy Boot (Secure Boot Off). Note the Windows 10 32 Bit architecture is non-standard and many systems build in 2012 or later have only Windows 64 Bit Drivers.

                                                                                                Use this setting for Windows 10 64 Bit.
                                                                                                When using Rufus to make a Bootable USB use the GPT Partition Scheme.
                                                                                                Use this setting for Windows 10 32 Bit.
                                                                                                When using Rufus to make a Bootable USB use the MBR Partition Scheme.

                                                                                                In other systems you may need to enter the UEFI BIOS setup to amend the settings.

                                                                                                The BIOS setup can also be accessed directly using [F2] when powering up the Dell system:

                                                                                                Look for a tab called Secure Boot, expand it, select Secure Boot Enable and change the setting to Enabled for Windows 10 64 Bit and Disabled for Windows 10 32 Bit. Select OK at any warning dialog box:

                                                                                                Legacy Option ROMs should be Disabled for Windows 10 64 Bit. Go to the general tab and select Advanced Boot Options, ensure Enable Legacy Option ROMs and Enable Attempt Legacy Boot are unchecked. For Windows 10 32 Bit both these checkboxes should be checked:

                                                                                                Next go to Boot Sequence and ensure the Boot List Option is set to UEFI:

                                                                                                You can also expand the System Configuration and check the SATA Operation. In most cases for a single drive it should be AHCI. If you have an older system with a small 32-64 GB SSD Cache Drive and a large capacity HDD, you may have a different SATA Operation such as RAID On (Intel Rapid Response Technology). It is recommended in most cases to replace both drives with a large capacity >250 GB SSD for optimal performance:

                                                                                                You an have a look at your Drives. In my case I have a single 128 GB SSD:

                                                                                                Select Apply:

                                                                                                Press OK:

                                                                                                Then Exit:


                                                                                                Lenovo UEFI BIOS

                                                                                                For a Lenovo we will use a Lenovo P320 ThinkStation with a 6th Generation Intel Skylake Processor as an example. When powering up the system press [F12] to get to the UEFI Boot Menu:

                                                                                                There is no mention about Secure Boot so we will have to Enter the Setup to check, the setup can be accessed directly by powering up and pressing [F1]:

                                                                                                The setup may also tell you if a SLIC Version of 2.1 (OA2.1 Marker) is present.

                                                                                                Select the Security tab and then highlight Secure Boot:

                                                                                                Ensure that Secure Boot is Enabled for a Windows 10 64 Bit install and Disabled for a Windows 10 32 Bit Install:

                                                                                                Use this setting for Windows 10 64 Bit.
                                                                                                When using Rufus to make a Bootable USB use the GPT Partition Scheme.

                                                                                                To install Windows 10 32 Bit you will need to go to the Startup tab and change the Boot Options:

                                                                                                If Secure Boot is Enabled, CSM will be locked to Disabled and Boot Mode will be UEFI only which are the correct settings for Windows 10 64 Bit.

                                                                                                For Windows 10 32 Bit installation you will need to enable CSM (this is what Dell call Legacy Roms):

                                                                                                A Legacy Boot must be used for Windows 10 32 Bit.

                                                                                                Use this setting for Windows 7 32 Bit.
                                                                                                When using Rufus to make a Bootable USB use the MBR Partition Scheme.


                                                                                                HP UEFI BIOS

                                                                                                When powering up press [F9] to get the Boot Menu and [F10] to get to the UEFI BIOS setup. On some older systems you need to power up pressing [Esc] to get to a startup menu which you can use to access the BIOS setup or Boot Menu respectively.


                                                                                                Creating a Bootable USB

                                                                                                Instructions to create a Bootable USB depend on the Partitions Scheme (UEFI or Legacy, UEFI for most computers), as well as the Operating System used to create the Bootable USB (WIndows 10 in most cases). There is also a dependence on the size of the install.wim or install.esd or install.swm files.

                                                                                                The Bootable USB needs to be FAT32 formatted in order to Boot using a UEFI BIOS with Secure Boot. FAT32 has an upper size limit of 4.0 GB. For the Direct download links in particular Microsoft have not carefully restricted the file size to less than 4.0 GB. Unfortunately this means that conventional utilities to create a Windows 10 Bootable USB on Windows, Linux and Mac OS won't work correctly.

                                                                                                On Windows

                                                                                                Rufus can be used directly to create the Bootable USB from the ISO Downloaded from the Windows 10 Media Creation Tool however additional workarounds will be required for the ISO downloaded via direct links as the install.wim exceeds 4 GB (the maximum size for FAT32).

                                                                                                Creating a UEFI Bootable USB – Windows 10 Media Creation Tool ISO

                                                                                                The install.wim or install.esd has to be less than 4.0 GB. Otherwise Rufus will make a NTFS formatted USB which will be rejected by Secure Boot.

                                                                                                Double click Rufus to launch it:

                                                                                                Accept the User Account Control Prompt:

                                                                                                Insert your USB Flash Drive and make sure it is populated under Devices:

                                                                                                Select, select:

                                                                                                Select the Windows2004 ISO and select Open:

                                                                                                Change the Volume Label to something more meaningful like Win-2004:

                                                                                                In order for the Bootable USB to Boot using a UEFI BIOS with Secure Boot (standard for all computers build after 2012) the Partition Scheme must be GPT and FAT32.

                                                                                                Select Start:

                                                                                                Select OK to begin creating the Bootable USB:

                                                                                                When it is Finished it will have a Status of Ready. You can now close Rufus.

                                                                                                You now have Windows 10 Installation Media and should now proceed to Performing a Clean Installation of Windows 10.


                                                                                                The install.wim exceeds 4.0 GB and has to be manually split into <4.0 GB chunks to fit on a FAT32 formatted USB. A number of manual steps are required.

                                                                                                This occurs quite often with the Direct Download Links ISO but is dependent on language. If your install.wim does not exceed 4.0 GB you can use Rufus directly (see above).

                                                                                                Double click Rufus to launch it:

                                                                                                Accept the User Account Control Prompt:

                                                                                                Insert your USB Flash Drive and make sure it is populated under Devices:

                                                                                                Select, select:

                                                                                                Select the Windows2004 ISO and select Open:

                                                                                                Select the checksum button to view the Checksum:

                                                                                                The SHA256 should match the one that Microsoft provide:

                                                                                                We can change the volume label to something more sensible.

                                                                                                The Bootable USB cannot be created directly with Rufus as it has an install.wim file which exceeds 4 GB. As a result Rufus will use the NTFS file system which will be rejected by Secure Boot.

                                                                                                We will instead use Rufus to setup a USB Flash Drive to use the GPT Partition Scheme and to be FAT32 Formatted and manually copy the Windows Installation files over with the install.wim being split between a install.swm and install2.swm file.

                                                                                                Change the Boot Selection to Non-Bootable. Ensure the Partition Scheme is GPT and ensure the File System is FAT32:

                                                                                                Delete the two autorun files on the Bootable USB:

                                                                                                Select Yes at the dialogue.

                                                                                                Now right click the ISO and select Mount (Windows 7 doesn't have the ability to mount ISOs directly. if making the Bootable USB on Windows 7 you will need to install Virtual Clone Drive in order to mount ISOs).

                                                                                                Copy the entire contents of the ISO (except for the install.wim within the sources folder):

                                                                                                And then paste to the USB:

                                                                                                If all files successfully copy across without error your isntall.wim < 4.0 GB and fits on a FAT32 formatted USB flash drive. Your installation media is complete.

                                                                                                If you are instead informed that the install.wim is too large to fit on the file destination system (FAT32). Select Skip:

                                                                                                Go to the sources folder of the mounted ISO and Copy the install.wim.

                                                                                                Paste it directly to C:\

                                                                                                Now right click the start button and select Windows PowerShell (Admin):

                                                                                                Accept the User Account Control Prompt:

                                                                                                This can be done by using the following command:

                                                                                                Dism /Split-Image /ImageFile:C:\install.wim /SWMFile:C:\install.swm /FileSize:4000

                                                                                                You may now close down the Powershell Prompt.

                                                                                                Windows 7 and Windows 8.1

                                                                                                Windows 7 DISM is out of date and does not include the split command.

                                                                                                We can get the functionality by using the wimlib library instead. Download the latest zip file for Windows. It should end in Windows-x86_64-bin.zip file.

                                                                                                Extract the folder and rename the extracted folder wimlib and copy it directly to the C:Drive

                                                                                                Go to the start menu and search for CMD, right click it and select Run As Administrator.

                                                                                                Accept the User Account Control:

                                                                                                Type in the following to change directory to the wimlib folder

                                                                                                CD C:/wimlib

                                                                                                Type in the following command to split the install.wim:

                                                                                                wimlib-imagex split C:/install.wim C:/install.swm 4000

                                                                                                You now have multiple install.swm files:

                                                                                                Now copy install.swm and install2.swm:

                                                                                                To the sources folder of the USB Flash Drive:

                                                                                                Your Windows 10 Bootable USB is now ready.


                                                                                                Creating a UEFI Bootable USB with Driver Pack Slipstream – Direct Download ISO

                                                                                                Driver packs can be slipstreamed into the install.wim of the direct download link ISO. The install.wim will once again exceed 4.0 GB and has to be manually split into <4.0 GB chunks to fit on a FAT32 formatted USB. A number of manual steps are required.

                                                                                                Note these instructions do not work on Windows 7 which has an older version of DISM.

                                                                                                Double click Rufus to launch it:

                                                                                                Accept the User Account Control Prompt:

                                                                                                Insert your USB Flash Drive and make sure it is populated under Devices:

                                                                                                Select, select:

                                                                                                Select the Windows2004 ISO and select Open:

                                                                                                Select the checksum button to view the Checksum:

                                                                                                The SHA256 should match the one that Microsoft provide:

                                                                                                We can change the volume label to something more sensible.

                                                                                                The Bootable USB cannot be created directly with Rufus as it has an install.wim file which exceeds 4 GB. As a result Rufus will use the NTFS file system which will be rejected by Secure Boot.

                                                                                                Note if using a Legacy Only BIOS you can change the Partition Scheme to MBR and leave the File System to NTFS and proceed using Rufus.

                                                                                                We will instead use Rufus to setup a USB Flash Drive to use the GPT Partition Scheme and to be FAT32 Formatted and manually copy the Windows Installation files over with the install.wim being split between a install.swm and install2.swm file.

                                                                                                Change the Boot Selection to Non-Bootable. Ensure the Partition Scheme is GPT and ensure the File System is FAT32:

                                                                                                Select Start:

                                                                                                Select OK to Create the Blank USB:

                                                                                                When done it will say Ready. Select Close:

                                                                                                Delete the two autorun files on the Bootable USB:

                                                                                                Select Yes at the dialogue.

                                                                                                Now right click the ISO and select Mount (Windows 7 doesn't have the ability to mount ISOs directly. if making the Bootable USB on Windows 7 you will need to install Virtual Clone Drive in order to mount ISOs).

                                                                                                Copy the entire contents of the ISO:

                                                                                                And then paste to the USB:

                                                                                                You will be informed that the install.wim is too large to fit on the file destination system (FAT32). Select Skip:

                                                                                                Go to the sources folder of the mounted ISO and Copy the install.wim.

                                                                                                Paste it directly to C:\

                                                                                                Select Continue to allow permissions:

                                                                                                Right click the install.wim and select Properties:

                                                                                                Ensure Read Only is not checked then select Apply:

                                                                                                Then select Continue:

                                                                                                We need to use PowerShell to split the install.wim file into multiple install.swm files that are less than 4 GB.

                                                                                                For select business models (OptiPlex, Latitude, Precision and XPS) you also have the option to download the Dell Driver Cab and we can slipstream this into the install.wim using a handful of lines of code. You will also need to download and install 7-zip in order to extract the drivers folder.

                                                                                                This guide focuses more on the Dell systems but it will also work with the Lenovo Business model if you rename the extracted folder Drivers and move it to the C:\ Drive the procedure will be identical.

                                                                                                On the Dell website select your model and then select Windows 10 64 Bit under Operating System and then Systems Management under category.

                                                                                                Select the Driver Pack and select Download:

                                                                                                You will need to extract these drivers. I recommend using 7zip for this.

                                                                                                Right click the CAB file and select 7-Zip and then Extract to " ":

                                                                                                You may get the Warning "There are some data after the end of the payload data". You can ignore this and select Close:

                                                                                                Open the extracted folder:

                                                                                                Select the Win10 folder:

                                                                                                Right click this folder and select rename, rename the folder

                                                                                                Select Start:

                                                                                                Ensure the Partition Scheme is MBR and the File System is NTFS:

                                                                                                Select Start:

                                                                                                Select OK to proceed making the Bootable USB:

                                                                                                When the Bootable USB is made Rufus will say Ready:

                                                                                                You may now close Rufus.


                                                                                                On Linux

                                                                                                If the install.wim of the direct download links often exceeds 4.0 GB conventional Bootable USB utilities like Uetbootin for example will either truncate the install.wim to 4.0 GB giving incomplete installation media which will naturally fail during installation or alternatively make the USB NTFS formatted which will be rejected by Secure Boot. In these cases the install.wim has to be manually split into <4.0 GB chunks to fit on a FAT32 formatted USB. A number of manual steps are required.

                                                                                                This occurs quite often with the Direct Download Links ISO but is dependent on language. If your install.wim does not exceed 4.0 GB you should skip the step to split the install.wim.

                                                                                                On Linux we need to use GParted to make sure our USB Flash Drive is formatted as FAT32.

                                                                                                Then as the install.wim file exceeds 4 GB we need to use the wimtools library to split the install.wim file to multiple swm files that are below 4 GB so that they can fit within the constrains of the FAT32 file system. Once we have this, we can copy all the files over and will get a USB Flash Drive that can Boot in a UEFI BIOS and Pass Secure Boot.

                                                                                                To check the ISO checksums. Open up the terminal and type in:

                                                                                                cd Downloads

                                                                                                Replace filename with the filename of your ISO:

                                                                                                sha256sum filename.iso

                                                                                                Close the terminal after you have verified the checksum.

                                                                                                Right click the Windows 10 ISO file and select Open with Disk Image Mounter:

                                                                                                Open the mounted ISO and go to the sources folder:

                                                                                                Right click the install.wim and select properties:

                                                                                                Look at the size of the install.wim. If it is less than 4.0 GB you will need to use GParted to make a FAT32 formatted USB but will be able to copy all the files from the ISO directly across to the USB without worrying about splitting the install.wim.

                                                                                                If it exceeds 4.0 GB then it is too big to fit on a FAT32 formatted USB flash drive which has an upper limit of 4.0 GB. Copy the install.wim over to Downloads.

                                                                                                We will need to split it using wimtools:

                                                                                                To install wimtools and gparted we need to use the terminal:

                                                                                                First we need to make sure the links to the repositories are up to date. To do this type in:

                                                                                                sudo apt-get update

                                                                                                On Fedora use dnf instead of apt-get.

                                                                                                Then [↵]

                                                                                                To authorise input your password and then input [↵].

                                                                                                Now type in:

                                                                                                sudo apt-get install wimtools

                                                                                                On Fedora use dnf instead of apt-get.

                                                                                                Now type in the following to split the install.wim into multiple .swm files:

                                                                                                Now we will launch GParted:

                                                                                                Input your password to authenticate:

                                                                                                To the top right, select your USB Flash Drive:

                                                                                                Right click it and if Format to is grayed out select Unmount.

                                                                                                Right click it and select Format to FAT32:

                                                                                                Then Apply:

                                                                                                Then Apply:

                                                                                                When done select Close:

                                                                                                Now copy all files from the ISO to the USB except the sources folder:

                                                                                                Create a new folder on the USB called sources:

                                                                                                Copy all the files from the sources on the ISO to the sources folder on the USB except for the install.wim which is too big for FAT32:

                                                                                                In its place copy the two .swm files:

                                                                                                Ensure all files are copied across there should be no progress indicator under the folder icon on the side panel.

                                                                                                You should now have a Bootable USB that can Boot within a UEFI BIOS with Secure Boot.


                                                                                                On Linux we need to use GParted to make sure our USB Flash Drive is formatted as NTFS.

                                                                                                To check the ISO checksums. Open up the terminal and type in:

                                                                                                cd Downloads

                                                                                                Replace filename with the filename of your ISO:

                                                                                                sha256sum filename.iso

                                                                                                Close the terminal after you have verified the checksum.

                                                                                                Right click the Windows 10 ISO file and select Open with Disk Image Mounter:

                                                                                                Open the mounted ISO and go to the sources folder:

                                                                                                To install gparted we need to use the terminal:

                                                                                                First we need to make sure the links to the repositories are up to date. To do this type in:

                                                                                                sudo apt-get update

                                                                                                Then [↵]

                                                                                                To authorise input your password and then input [↵].

                                                                                                Now type in:

                                                                                                sudo apt-get install gparted

                                                                                                Followed by [↵]

                                                                                                Input:

                                                                                                y

                                                                                                Followed by [↵]

                                                                                                Both programs are now installed, you can close the terminal.

                                                                                                Now we will launch GParted:

                                                                                                Input your password to authenticate:

                                                                                                To the top right, select your USB Flash Drive:

                                                                                                Right click it and if it is mounted, select Unmount.

                                                                                                Right click it and select Format to NTFS:

                                                                                                Then Apply:

                                                                                                Then Apply:

                                                                                                When done select Close:

                                                                                                Ensure all files are copied across there should be no progress indicator under the folder icon on the side panel.

                                                                                                You should now have a Bootable USB that can Boot within a Legacy BIOS.

                                                                                                On Mac OS, the Windows 10 Download Links will be direct download links.

                                                                                                To check the Checksum we will use the Terminal Go to Launchpad and then select Other:

                                                                                                Then select the Terminal:

                                                                                                Type in:

                                                                                                cd Downloads

                                                                                                Then type in:

                                                                                                shasum -a 256 YOURISOFILENAME.iso

                                                                                                I recommend using copying your ISO file name and pasting opposed to trying to type it out. Once done press [↵].

                                                                                                Select OK:

                                                                                                The ISO Checksum should match Microsoft's website. If it does not retry the download as your ISO is corrupt:

                                                                                                For a UEFI BIOS the Bootable USB needs to be FAT32 formatted and setup to use the GPT Partition Scheme.

                                                                                                The FAT32 file system has an upper limit of 4096 MB. Unfortunately Microsoft have made the install.wim on the ISO file exceed this limit causing multiple issues making Bootable USBs.

                                                                                                To rectify this we need to split the install.wim into smaller install.swm files. Double click the ISO to open it:

                                                                                                Go to the sources folder:

                                                                                                Look for the install.wim and copy it to the Downloads folder:

                                                                                                On a Mac system we need to install a utility called wimlib which we can use to split the install.wim file into two smaller install.swm files. To do this we first need to install brew (which allows for commands similar to sudo on Linux). Open up the terminal and type in:

                                                                                                /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

                                                                                                Then press [↵]. Input your password when prompted to authorise the install:

                                                                                                Select [↵] to continue:

                                                                                                Brew will install:

                                                                                                Once Brew has installed, use it to install wimlib. Type in:

                                                                                                brew install wimlib

                                                                                                Then press [↵].

                                                                                                wimlib will now be installed:

                                                                                                Now type in:

                                                                                                wimlib-imagex split Downloads/install.wim Downloads/install.swm 4000

                                                                                                Then press [↵].

                                                                                                Wait for wimlib to finish splitting the install.wim file into the two install.swm files. You will now have two install.swm files.

                                                                                                We now need to create a blank FAT32 formatted USB Flash Drive. Unfortunately if you use the GUI to make a FAT32 formatted USB. The Windows 10 Install will hang at copying files giving the error message. This means the USB flash drive is not properly FAT32 formatted:

                                                                                                Windows could not prepare the computer to boot into the next phase of installation

                                                                                                We can fortunately use the terminal to create a FAT32 formatted USB Flash Drive correctly. Insert a USB Flash Drive and open up a terminal and type in:

                                                                                                diskutil list

                                                                                                Press [↵] to continue:

                                                                                                Look for the number of your disk, in most cases it will be disk2 (it should be external and the size as expected):
