Written Guide

This will perform a clean installation of Windows 7 64 Bit removing all data on your system’s drives.

If you have not backed up your data and you have came to this guide because your system cannot boot. Please run the preboot diagnostics.

And attempt data recovery to an external hard drive using Fedora before proceeding:

Part 1: Determining whether your System Supports UEFI and Secure Boot

The UEFI BIOS and GPT partition scheme should be used where possible with Windows 7 64 Bit. You may or may not have these technologies depending on the age of your system. For reference:

  • 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

This guide focuses on a UEFI BIOS, if you have an even older Dell System than 2011, ignore any mention of the words UEFI, Legacy ROMs and Secure Boot as the technologies are not available in your system. Such systems have a Legacy BIOS (non-UEFI) BIOS. Installation instructions are otherwise identical however the installation media for them needs to be made using the MBR partition scheme and NTFS file format opposed to the GPT partition scheme and FAT32 format.

On a Dell system press [F2] to enter the UEFI BIOS setup, I’ll demonstrate using the newest hardware supported to run Windows 7 64 Bit – the OptiPlex 7040:

Windows 7 64 Bit does not support Secure Boot, it must be Disabled in the UEFI BIOS setup for Windows 7 64 Bit Installation. Look for a tab called Secure Boot, expand it, select Secure Boot Enable and change the setting to Disabled. Select OK at any warning dialog box:

Legacy Option ROMs must be enabled for Windows 7 64 Bit. Go to the general tab and select Advanced Boot Options, ensure Enable Legacy Option ROMs are Enabled. You should leave Enable Attempt Legacy Boot unchecked:

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

Select Apply:

Press OK:

It is also worth looking at your Drives here – in my case I have one 128 GB SSD drive that is M.2, others may have a HDD and a low capacity 32-64 GB SSD Cache Drive:

For a single Drive I can use RAID On or AHCI. If you have a small capacity SSD and a large HDD you would need to select RAID On (sometimes called Intel Smart Response Technology):

Now exit the UEFI BIOS setup to save the changes:

Part 2: Preparing Up to Date Installation Media

Using updated installation media will reduce the hassles of Windows 7 Installation Failure due to lack of native driver support for systems with a UEFI BIOS and greatly reduce the installation time due to the inefficiencies of Windows Update. Dell have created installation media updated until January 2016 with driver support up to 6th generation Intel Skylake Hardware. I call this the Dell Windows 7 Professional Skylake Reinstallation .iso. On a Dell it is recommended to use this opposed to any older installation media.

On a non-Dell you’ll need to use the Generic Microsoft Retail Installation Media and add USB 3.0 Driver support, the guide for downloading the media from Microsoft will instruct you in doing this:

Part 3: Booting from a Bootable USB

Power Down your Dell an Insert your Windows 7 Installation USB and make sure no other USB Devices are connected except for the Keyboard and Mouse. If using a Dell OptiPlex model (or other Desktop) I recommend using the back USB Ports as these are directly on the System Board and Avoiding the Front Ones for Windows 7 Installation.

Hold [F12] while powering up your computer:

You will now enter the UEFI BIOS Boot Menu:

Notice that it says to the top that the Boot Mode is set to UEFI and Secure Boot is OFF. Press [↓] until you get to your USB Flash Drive (in my case it is a Sandisc Cruzer Glide 16 GB), ignore any listings sunder Legacy Boot.

Some systems may tell you to press any key to continue Booting from USB, if they do press the space bar.

Part 4: Early Installation

You will get a black screen that says “Windows is Loading Files.”

Then one that says Starting Windows.

You will then be prompted for your language, time and currency format and keyboard settings, amend these as desired. If you use an English .iso it’ll be set by default to English (US), I’m going to change to English (UK):

Select Install Now.

You will get a Setup is Starting Screen:

You may get a file asking you what Edition of Windows you wish to install. This depends if the installation media has an EI.cfg file – the EIF.cfg file is a text file which automatically selects the option at this screen. In my case I am going to install Windows 7 Professional using Downgrade Rights from Windows 10 Pro OEM on a Dell OptiPlex 7040:

Read the license, check to select and then select Next.

Next select Custom (Advanced).

Part 5: Loading SATA Drivers and Deleting Partitions

Warning: This step will result in data loss of internal drives.

If you are clean installing Windows due to a Boot Problem and cannot backup your data as Windows cannot boot the follow my guide Data Recovery using Fedora which uses a Bootable Fedora Live Linux USB which can access the HDD/SSD in many cases when Windows cannot.

If the Windows 7 installation media can see your SSD/HDD/HSSD on the next screen then you do not need to load a SATA preinstallation driver as it’s incorporated. This should be the case for the Dell Skylake Reinstallation .isos which have support for up to 6th generation Intel Skylake systems.

Loading SATA Drivers

Most UEFI systems have hardware substantially newer than Microsoft’s Windows 7 Installation Media from 2010 and as a consequence Windows 7 does not have the SATA drivers required for your Storage Controller. It cannot read your SSD/HDD/HSSD.

If no drives are listed on the “Where do you want to install Windows?” screen then you must select Load Driver and select the SATA drivers from a USB stick. The SATA drivers essentially allow Windows to recognise the hard drive controller on the motherboard and thus allow Windows to view the drive letting you proceed with the install.

Note the error message here says:

“No Drives were Found. Click Load Driver to Provide a Mass Storage Driver for Installation”.

Quite often other error messages show such as

“A media driver your computer needs is missing”

“A required CD/DVD drive device driver is missing”

These normally mean your installation media is corrupt and are not because you need to load a driver. “A required CD/DVD drive device driver is missing” quite often shows on Desktops when the Front USB Ports are used, move your Bootable USB to the back USB Ports instead and restart the computer.

Go to downloads.dell.com

Press [Ctrl] and [ f ] to do a search. I’m going to type in 7040 as I am going to clean install Windows 7 64 Bit on this model.

You can scroll down until you get to Serial ATA:

Alternatively press [Ctrl] and [ f ] and do a search for F6 (these were called F6 drivers as they used to be loaded in Windows XP by pressing F6 and using a Floppy Drive!)

You must extract the driver as the Windows Setup cannot read .exes. Normally this can be done by launching the setup:

Accept the User Account Control:

Select Extract:

Specify the location:

Copy the extracted folder to your Windows 7 Bootable USB.

Look through the contents of the extracted folder, there is normally a drivers subfolder and a Windows7-x64 subfolder:

It’s contents should look like:

This is the format the Windows setup can read. Select Load Drivers:

Then Browse:

Then navigate to the subfolder containing the drivers:

Ensure that “Hide drivers that are not compatible with hardware on this computer is ticked” (it should be set like this by default). Select Next:

The Storage controller is now recognised so the internal HDDs/HSSDs etc all show up. If it is all unallocated space as shown select Next.

If instead you have a previous version of Windows on your drives screen may instead look like this.

Warning 2: This step will result in data loss of internal drives.

You can perform a Low Level Format using the Windows Installation Media by Deleting all the partitions on the drive. You should do this if:

  • You are clean installing the latest version of Windows 10 on your PC.
  • You are sure your old version of Windows wasn’t infected with malicious software.
  • You are keeping your computer…

You should instead quit Windows Installation and perform a Secure Wipe using Dell Data Wipe or Parted Magic if:

  • You are clean installing the latest version of Windows 10 due to a malicious software.
  • You have bought your computer second hand (and are not sure what the last user has had on the PC).
  • You are planning selling your computer on (and don’t want personal data passed on).

To perform the Low Level Format using the Windows Installation Media select every partition on Drive 0 (or the desired Drive you wish to install Windows if you have a system with a multiple drive configuration) and systematically delete any partition.

Delete all Partitions including Recovery Partitions, these are for old obsolete versions of Windows and no longer required.

If multiple drives show you may have a SSD and a HDD.

If your SSD is >128 GB install Windows 7 on your SSD as it’ll result in optimal performance.

If it is 32-64 GB it should be a cache drive. Remove all partitions on it and on the HDD. Then install on the HDD. The SATA Operation needs to be in RAID. Notes on setting up Intel Rapid Storage Technology to use the SSD as a cache drive will be given later.

Part 6: Middle of Installation

You will then a screen telling you the progress of the install and Windows will restart once:

Type in your “username”, by default the PC name will be “username-PC” but you can change this as desired.

Next type in your password, retype it and leave yourself a hint.

Alternatively just select next (to have no password – not recommended but optional). Personally for convenience I tend to leave the password blank and add one after the installation of Windows 7, drivers and updates as you will be prompted to restart your computer several times.

Part 7: The Product Key

You should only input a Product Key at this stage if your License is Retail Full, otherwise select Skip for OEM Licenses and Retail Upgrade Licenses. Note this screen will not show at all if using Dell Windows 7 Reinstallation Media. Installation without a Product Key will give a 30 Day Trial (we only need about 30 mins of this trial before we go ahead and activate Windows).

Part 8: End of Installation

You will then be asked about Windows Update settings its generally best to go with recommended.

Then select your time and date settings.

The next screen should be about connecting to the internet and/or connecting to a wireless network. In most cases Windows 7 won’t have the driver inbuilt for a UEFI system and this screen will not show. The setup will Finalise and restart taking you to the Windows Desktop.

Part 9: Install the Latest Security Updates

If you’ve followed my guide to make Windows 7 Installation Media these updates should be copied onto your Windows 7 Bootable USB and installed in the order KB3020369, KB3125574 (restart), KB2639308, KB2670838, KB2729094, KB2834140 (restart) then IE11-Windows6.1 simply double click them and follow the on screen instructions to install them. After IE11 is installed, install the Microsoft .Net Framework. If you don’t have them and need to Download them Windows 7 64 Bit and Windows 7 32 Bit Download links are below (you’ll need to use another computer with internet access to Download these):

Part 10: Activation

If you have used OEM Reinstallation Media on an OEM System e.g. the Dell Windows 7 Professional Reinstallation ISO or DVD on an eligible Dell System, Windows 7 should be activated offline automatically using OEM System Locked Preinstallation.

If you have used Retail Installation Media with a Full Retail Product Key you should automatically activate Windows 7 when online.

If you have used Retail Installation Media on an OEM System e.g. the Microsoft Windows 7 Retail ISO or DVD on an eligible Dell, HP or Lenovo System, you will need to manually apply OEM System Locked Preinstallation.

These are available here:

https://drive.google.com/file/d/1d2xFAA6aDJu3PEtLD2Sv4WUfxg5lTwBl/view?usp=sharing

Extract this folder, select your OEM, in my case Dell, select your Edition in my case Pro as I am using Windows 10 Pro Downgrade Rights and copy the OEM folder to the C:\Drive

Open the OEM folder on the C:\ Drive. Right click the slp.bat file

Select Run as Administrator:

Select Yes to Allow the Command Prompt to open:

The OEM Certificate will be installed. Select OK:

The generic OEM SLP key will be installed (dell use this key for every Dell shipped with Windows 7 Pro from factory). Press OK:

Press any key to continue. The Command Prompt will be closed:

Right click the start button and select Properties:

Windows will now be activated using OEM SLP, the product ID will contain OEM-899

If you have used Retail Installation Media with a Retail Upgrade Only Product Key then you may have activation issues after performing a clean installation. You should activate by the Command Prompt instead.

You may get this is you attempt to activate normally, to get around this, we can use the Command Prompt:

key-issue

Press the Start Button and in the search box type in CMD.

Right click CMD.exe and select run as an administrator. This will open up the elevated command prompt accept any user account control prompt.

1

To input your product key type:

slmgr /ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx

Where xxxxx-xxxxx-xxxxx-xxxxx-xxxxx is your product key and then press Enter.

2

Select ok and then to activate type

slmgr /ato

This will activate your product.

3

Part 11: System Drivers

You should now look at installing your system drivers starting with the Dell System Software (if applicable for your system) and the Chipset drivers. See Driver Installation Order for more details.

If using a SSD Cache Drive be sure to set it up after driver installation following the instructions here.


Part 12: Security

You may have installed Microsoft Security Essentials for Windows 7 above to give your system base system security. However Windows 7 isn’t as Secure as Windows 10 and you may want to install another security product then I recommend Malwarebytes’ AntiMalware. There is a free version which only does an on demand scan or a paid version which does Realtime Protection. Below is an affiliate link:

23 thoughts on “Windows 7 64 Bit Installation on a UEFI BIOS (Up to 6th Generation Intel Systems)

  1. I am a dell using costomer if any one help my problem my laptop inspiron 1545 i go to my restall my windows7 system he is not done my laptop is telling me boot manager is missing and i go in repair ways but not resolve and will chek my system setup utility cd or dvd disc is break and damage in bad condisition how i do my setup file in copy cd or dvd and iam a first time in dellsupport site we are confuse how i go my servicetags no is cdqm4bs so plz help me 10 days i am not use my laptop give me my download links

  2. I have a Latitude E6410 with Win 7 Home and I’m trying to upgrade to Win 7 Professional 64. The E6410 is running BIOS A16 and appears to have UEFI but no settings for secure boot. I’ve placed the iso on a USB stick and that appears in the boot list when UEFI is enabled. It loads the installation files from USB no problem but then hangs at the Starting Windows screen. This is exactly what it does with a DVD install. I was hoping that the USB install would work but no luck. Any ideas …?

  3. Helo?
    Sir my system Dell GX520 is not install for sound driver in windows7 64bit.plece help me.

  4. ‘Often the network drivers are needed to be installed’ – thats indeed a problem after my clean install…apparently cant update windows without the internet connection. the network drivers are on the Dell installation drivers&utilities cd, however, when i’ve nstalled them my laptop still fails to locate any wifi connections. is it the problem be with the wifi driver (dell wireless 1702 802.11 b/g/n..?) – i even downloaded the latest version of it from the dell website yet it still says ‘no connections are available’. any advice, Philip?

    1. oh yes finally success – there were no Wireless connections..in fact, one of the oldest network drivers worked (not the most recent one!). the dell site drives me crazy – too many drivers available for my service tag and not all of them work, so one only finds out ‘by trial and error’.

      1. Thank, you very much, super—- but: WIN7-32 doen’t handle USB 3.0

        I’d like to have a clean install on a E7470 Latitude, but after WIN7 boot process started USB 3.0 makes it impossible to go on.

        Thank you for help

  5. Many thanks for the great work you do here. It is extremely helpful. I really appreciate what you do here Philip. I can see how bad the Dell support is according to the things I have learned here. I bought a Dell Inspiron 15 5559 i5-6200u laptop with Ubuntu pre-installed couple of days ago. I installed windows 7 following your guide here, adjusting the BIOS as you instructed here, from a bootable DVD I already had. It is not downloaded from links of this site (the .iso). I cannot remember where I downloaded that ISO exactly. I had it for some time with me. That ISO contains this file name “en_windows_7_ultimate_with_sp1_x64_dvd_u_677332”. I can remember that the site where I downloaded it say it is an untouched iso.

    So I installed windows from the dvd and skipped the activation part & the windows got installed without any problem. But when I tried to activate windows with Windows Loader by Daz v2.2.1 & v2.2.2 both gave me messages that keys have been successfully installed and to restart. When I restart windows comes to the loading point and crashes giving a blue screen. I re-installed windows from the same dvd & also tried to activate with the ABR Program. Even though the command prompt looked like it did the trick, after restart windows is still not activated. Tried to activate 2-3 times. No fruition. Activate period only 3 days remaining. Thank god the ABR program did not crash windows.

    Question 1 – Will I be able to activate this installation? The installed windows gives the product ID “00426-OEM-8992662-00400”.

    Since the above installation failed to activate I have downloaded “Dell Windows 7 Ultimate 64 Bit SP1 USB3.0 OEM Reinstallation.iso” you have provided in another guide on this site. Now I have a windows 7 usb 3.0 ISO & a usb 3.0 pendrive.

    Question 2 – Will i be able to create the windows 7 bootable usb 3.0 drive, using a desktop computer which only has usb 2.0 ports?

    Question 3 – Provided that I am able to create the bootable usb 3.0 drive from Dell ISO, using a usb 2.0 computer, will i be able to activate windows from the ABR Program?

    You have mentioned in another guide that some people download the ISO’s with less capacity. Example: if the ISO should be 4.3GB, the downloaded ISO is only 4.1GB. Yo have mentioned that this is not the full ISO’s and some parts missing in those ISO’s with less capacity.

    Question 4 – “Dell Windows 7 Ultimate 64 Bit SP1 USB3.0 OEM Reinstallation.iso” you have given in another guide on this site, according to you, have 5.4GB. But what I downloaded is only 5.23GB. Is there an issue in the capacity of the ISO here?

    Thank you for your help.

    1. The Dell Windows 7 OEM System Locked Preinstallation from a Dell Windows 7 Reinstallation DVD or ABR program will not work on your Dell as the system is not shipped with Windows 7 or Windows 8.1/10 Pro. The UEFI BIOS therefore doesn’t contain the markers and won’t activate.

      The USB can be made on a computer with USB 2.0 ports.

      The Windows 7 64 Bit Home Premium and Professional .iso are 5.23 GB.

      1. The .isos don’t have USB 3.0 added despite the names. The WinImage program did something different than expected (essentially copying the DVD to a .iso again opposed to the USB). They are however all the correct Editions.

  6. Philip – thanks for all you do. I have a Dell Latitude E6410 – the hard drive died and has been replaced, but I am having trouble loading Windows 7 or 10 64 bit on the new hard drive. I obviously do not have recovery from the dead drive. BIOS is A16 (Legacy), SLIC 2.1, SMBIOS 2.6, and there is a product key for Windows 7 on the back and I understand from your site that Dell employed a general Windows 7 license beginning with 32KD2. When I try to load Windows 7 or 10 (USB or DVD), I see the Windows logo but then nothing happens – no circle of dots below, nothing. Any ideas? Do I need to slipstream drivers or something?

      1. Hi, Philip. I’m performing a clean installation of Windows 7 64-bit on a laptop running SMBIOS 2.6. I believe it has UEFI functionality since I entered the BIOS and found a place where I could enable or disable UEFI support. I’m also installing a brand new SSD. I’ve been following your instructions dutifully. I created a USB installer with Rufus and selected GPT for the partition scheme. I’m at the “Where do you want to install Windows?” screen, and it lists two partition types: “MSR (Reserved)” and “Primary.” When I highlight the MSR partition and click delete, a warning tells me that it “might contain recovery files, system files, or important software from your computer manufacture.” I don’t understand how a brand new SSD could have any of this. I did some research on the MSR partition, but still feel unsure of what to do. What would you advise? Should I leave the partition alone or should I delete it?

      2. It sounds like its a used SSD (check that you don’t have multiple drives). You should delete all partitions on it.

      3. Hi, Philip. Thanks for your help and the prompt reply. I deleted the partitions as you suggested and continued with the installation. Everything went smoothly. After installation, I booted from the USB again and proceeded to the partition screen to see how things would appear. I had three partitions: System, MSR (Reserved), and Primary. So everything seems normal. All I can think is that I must have begun a clean installation a year ago but never finished for some reason. (I have kept the SSD in its original packaging but it’s clear that I had opened it at some point.)

        I have a question about Part 9: “Install the Latest Security Rollup.” I skipped this step because, I assume, the WSUS updates contain these essential updates. Am I correct?

  7. i am dell 3470 8th generation windows 7 installing but key board mouse not working pl z help proceed in windows 7 installing guide
