Windows 8.1 Installation with Notes on UEFI & SecureBoot


This guide assumes you are using Windows 8.1 installation media from the Windows 8.1 Media Creation Tool which addresses issues in older installation media; it does not support Windows 8.0 media or Windows 8.1 media and both should be considered to be obsolete.

This guide will take you through Clean Installation if you have not backed up your data and do not have the installers for any software of system drivers i.e. are not ready for clean installation take your time and see the steps to prepare in A Clean Install of Windows 8.1.

Part 1: Determining whether your System Supports UEFI and SecureBoot

The UEFI BIOS and GPT partition scheme should be used where possible with Windows 8.1 64 Bit and SecureBoot should be enabled. You may or may not have these technologies depending on the age of your system. Dell note the date of their systems on their FTP Website:

http://downloads.dell.com/published/Pages/index.html

For example the Inspiron Desktop range:

1a

Systems Newer than 2012

These systems will have the newer security technologies associated with a UEFI BIOS. The UEFI BIOS settings with SecureBoot should be correctly setup by default from factory settings for any system shipped with Windows 8.1 64 Bit.

If you have a 2012 system shipped with Windows 7 64 Bit and want to install Windows 8.1 64 Bit or have tinkered about with your UEFI BIOS settings alter them as appropriate see Enable UEFI/SecureBoot.

UEFI and SecureBoot do not support Windows 8.1 32 Bit. The 32 Bit version should only be installed on weak hardware (such as tablets) or legacy hardware (which do not support these new technologies).

If you wish to cripple new hardware by installing 32 Bit Windows 8.1 you will need to Disable UEFI/SecureBoot.

Systems Older than 2012

For a legacy system BIOS that is a BIOS older than 2012 you will not have a UEFI compliant BIOS. Therefore UEFI and SecureBoot won’t be enabled.

Part 2: Booting from a Bootable USB/DVD

Power down your computer. Hold F12 while powering up your computer (at the Dell BIOs screen).

Dell BIOS Screen

Follow the instructions below to Boot either via UEFI or Legacy respectively.

Variant A: UEFI Boot

If your system is newer than 2012 its recommended to use a UEFI Boot and a GPT partition scheme; this is faster and more reliable. The boot manager should mention a UEFI Boot similar to below.

Note UEFI may not work with a DVD and you should Install from a USB.

Press the ↓ arrow and select your Windows 8.1 Bootable USB Flash Drive and press [Enter]

vlcsnap-2015-02-26-02h38m50s185

Variant B: Legacy Boot

For systems older than 2012 you will have to just use the legacy boot with the MBR partition scheme which will be listed by default. There will be no mention of Legacy or UEFI Boot but the boot option will be legacy.

If you wish to install Windows 8.1 32 Bit (unrecommended) on a 2012 or later system you will need to disable SecureBoot and enable legacy boot options.

Press the ↓ arrow and select your Windows 8.1 Bootable USB Flash Drive or DVD and press [Enter]

vlcsnap-2015-02-26-02h53m10s76

Select boot from CD/DVD or from USB respectively.

Press any key when prompted such as “h" when it says Press any Key to boot from CD/DVD.

Part 3: Beginning the Installation

You will get a black screen that says Windows.

8-1

Change the Time and Currency format and the Keyboard to your desired country. When ready select next.

8-2

Select Install.

8-3

Part 4: The Product Key

This is a part which has led to much user confusion, mainly to previous Microsoft mistakes in older installation media. Your key should automatically be input if you have an OEM license or you have to manually type it in for a retail license. You may also trial with a generic product key. Notes in all cases are given below after description of Edition.

Edition

There are 7 Windows 8.1 “Editions” unfortunately one of these “Editions” is called Windows 8.1 however marketing often refers to the whole Windows 8.1 Product Family as Windows 8.1 hence theres a great deal of confusion about Edition particular for the OEM license.

2 “Home” Editions are OEM only and Microsoft currently do not provide a Digital download for these:

  • Windows 8.1 with Bing
  • Windows 8.1 Single language with Bing

The other 3 “Home” Editions have a digital download:

  • Windows 8.0/8.1
  • Windows 8.0/8.1 Single Language
  • Windows 8.0/8.1N

There are also 2 “Professional” Editions which have a digital download:

  • Windows 8.0/8.1 Professional
  • Windows 8.0/8.1 ProfessionalN

Users unfortunately do not know what “Home” or “Professional” Edition they have and this is discussed in more detail with the Windows 8.1 Media Creation Tool.

Variant A: OEM License

If your system was sold by Dell with Windows 8.0/8.1 you will have a Windows 8.0/8.1 OEM “Edition” License the System Locked Preinstallation SLP UEFI-BIOS Embedded 25 Digit System Locked Preinstallation Key. This SLP key will be automatically input and you won’t be asked for a product key.

If you are asked for a product key for the OEM license you likely have used a .iso of the wrong “Edition”.

Variant B: Retail License

For the Retail Edition you’ll have to enter your product key.

8-4

Variant C: Evaluation

The generic Windows 8.1 product keys allow for evaluation of Windows 8.1 or perhaps only a quick test:

  • Core=334NH-RXG76-64THK-C7CKG-D3VPT
  • Core N=6NPQ8-PK64X-W4WMM-MF84V-RGB89
  • Professional=XHQ8N-C3MCJ-RQXB6-WCHYG-C9WKB
  • Professional N=JRBBN-4Q997-H4RM2-H3B7W-Q68KC
  • Core Single Language=Y9NXP-XT8MV-PT9TG-97CT3-9D6TC

These keys will allow installation only but not product activation which is covered later. They are useful to begin a trial/evaluation.

Part 5: License Agreement and Custom Install

Select Next. Read and accept the license and then select next

8-5

Select custom install (advanced) and then select next

8-6

Note select Custom (advanced) even/especially if you are “upgrading" from 7 to 8.1. There are always some bugs when selecting “Upgrade" on this screen and this seriously hinders your systems performance.

Part 6: Loading SATA Drivers and Deleting Partitions

For newer systems you will likely need to load SATA drivers. Windows 8.1 should have the inbuilt SATA drivers for old installation media. You’ll need to then decide how you’re going to partition the drive. I recommend clean installation but you may preserve your files with a Windows.old folder.

Loading SATA Drivers

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.

If instead you get the error message at the bottom of this screen saying “We couldn’t create a new partition or locate an existing one. For more information, see the Setup log files” see We couldn’t create a new partition or locate an existing one. For more information, see the Setup log files. This is quite a common error message for the Windows 8.1 setup.

8-7

See Downloading, Preparing an Loading SATA Drivers if you haven’t prepared the SATA USB stick in advance. Windows 8.1 has many SATA drivers inbuilt particularly for older systems and hence many systems don’t need SATA drivers loaded during installation. Ensure that “Hide drivers that are not compatible with hardware on this computer is ticked" (it should be set like this by default).

8-8

Select all the drivers listed and then click next. It will take you back to the “Where do you want to install Windows Screen?" this time showing the hard drive.

You can then select “Drive Options" which will allow you to delete or format partitions if any are present aswell as create new ones if there is unallocated space on the hard disc.

8-9

8-10

Variant A: Clean Installation Recommended

If performing a clean install on a drive that had Windows XP/Vista/7 or 8.1 factory installed you will encounter several factory installed partitions.

I recommend selecting and deleting all these partitions as they are a waste of hard drive space and non-functional after manual Windows installation. I recommend installing Windows 8.1 all the unoccupied space so that it occupies the entire hard drive. This will allow Dell Backup and Recovery to be installed later on to make a new recovery partition.

Note 1: There may also be a small diagnostics partition on older systems for the F12 preboot diagnostics which can be deleted. These diagnostics can be launched from a bootable USB/CD. If you ever need to launch these diagnostics you can follow my instructions in F12 preboot diagnostics

Note 2: After all of these are deleted you can select new to create a new partition on the hard drive and select next for installing Windows. When you install Windows 7 it will make a small system reserved partition of 100 MB, don’t worry about this as it is normal operation.

Note 3: If you have securely wiped your systems HDD or replaced the hard drive/solid state drive (recommended) you can directly select new to create a new partition on the hard drive and select next for installing Windows.

Variant B: Preserving Files in a Windows.old Folder

Note if you have not backed up your files (unrecommended) and want to later restore them don’t opt to delete or format the drive, just select the largest partition and select next.

All the folders/files from the former Windows installation will be relocated to a Windows.old folder. The desired files can be copied from Windows.old to their desired location after Windows installation.

Variant C: Dell Systems with Media Direct

If you are installing on a Media Direct system select the largest partition and select next, do not delete partitions as the Media Direct disc has set them up.

Part 7: Middle of Install

You will then a screen telling you the progress of the install.

8-12

The computer will then restart.

If after the start you get an error message saying “Partition Table not Found” this is because your boot sequence is incorrect.

The computer has used the Legacy boot which can only recognise the MBR partition scheme instead of the UEFI boot which can recognise the GPT partition scheme.

You need to amend the settings in the BIOS setup so the system boots to UEFI on

8-13

If after the start you get an error message saying “Partition Table not Found” then your boot sequence is incorrect.

The computer has used the Legacy boot which can only recommend MBR instead of the UEFI boot which can recognise the GPT partition scheme and you need to amend the settings in the BIOS setup so the system boots to UEFI only.

A black Windows screen will appear and the system will do some preparations such as getting the devices ready.

8-14

Part 8: Personalisation and Setting Up Accounts

You will then be prompted to type in your computers name and select a colour scheme.

vm1

You can then select express settings (red) or customise (green) to suit your preferences.

reset11

If you select customise:

Customise0

You will be presented with the next 4 screens:

Customise1 Customise2 Customise3 customise4

One thing to notice about Windows 8.1 when changing the settings is that it is very touch screen optimised, you can move the sliders along with your finger if using a touchscreen, otherwise just click them with the mouse.

There are 2 login scenarios a Microsoft Account and a Local Account. The Microsoft Account is recommended in most cases as its linked to Microsoft email services, Microsoft Office services and importantly Microsoft OneDrive cloud services. Use of a Microsoft Account gives the best Microsoft Service experience. The local account does not have such tight integration with Microsoft cloud services and is perhaps recommended for a public shared computer or for enterprise use. You will only be offered to login to a Microsoft Account if you are online.

Microsoft recommend the utilisation of a Microsoft Account for the best experience with their other services. If however you want a generic recovery partition without your Microsoft Account details I recommend making a local account (variant C) without a password and switching to a Microsoft Account after the creation of a Recovery Partition with Dell Backup and Recovery.

Variant A: Online – Microsoft Account

If you are online you will then be prompted to enter your email address and sign in with a Microsoft Account. The Microsoft Account is recommended for easier use with Outlook, OneDrive, the Windows Store and to sync your Windows settings across devices:

account1

account2

Enter your email address and select next, it will then search for a Microsoft Account (if you use a Microsoft email or XBOX live it will be one). If you don’t have a Microsoft account you can sign up for one.

If you sign in with a Microsoft Account, additional security measures are usually put in place such as validation of your phone number associated with your Microsoft Account. Windows 8.1 only lets you log in when the validation checks are complete.

Usually the checks are done with a mobile phone. You are prompted to enter the last 4 digits of your phone number:

ma1

A text is sent to you and you need to input it:

ma2

Once you have input the correct code select next.

Variant B: Offline – Local Account

Alternatively if you are offline you will only be given the option to sign in with a local account.

reset13

Upon first connection to the internet you will be given the option to convert your Local Account into a Microsoft Account.

Variant C: Online – Local Account

To sign in without a Microsoft Account, select create a new account:

withoutma

At the bottom select sign in without a Microsoft Account:

withoutma2

Create a new username and password:

withoutma3

Part 9: End of Install

Your settings will finalise and your Windows 8.1 Apps will be installed.

reset14

If signed in with a Microsoft Account you will get the screen to reserve:

Windows10 Reserve

After selecting reserve you will be informed your free upgrade is reserved:

windows102

You should now be logged into Windows 8.1.

8-24

You should now look to using the WSUS Offline Update to patch Windows 8.1 and then start to installing your system drivers starting with the Chipset drivers. After the system drivers are installed, Dell Backup and Recovery should be installed to make a new Recovery Partition from the Clean Installation. See the full A Clean Install of Windows 8.1 for more details if you need additional guidance for these steps.

  1. fabulous guide, my inheritted Studio 1537 is now compfortably running 8.1🙂. My only add-on would be to remind novices such as my self to insert the Windows media before powering off for the first time.
    Mr Yip you are truly a star.

  2. I will be using this guide sometime this week as my new XPS 8700 desktop is now in a box at home. I plan to install 8.1 on the 256 GB SSD which will be installed in the computer’s mSATA slot (as delivered, 8.1 is installed on an internal 1TB spinning hard disk). I plan to request the 8.1 resinstallation DVD from Dell later tonight. The computer and its media have literally never been used so I look forward to a streamlined installation process.

    I’m a little wary of the whole process because, oddly enough, your writing here and elsewhere makes it seem so easy. Any additional hints for exactly what I am planning?

    Thanks so much for your work and I will report back.

    1. If you want to clean install download a Windows 8.1 .iso and make a bootable .iso opposed to requesting a DVD from Dell. The Reinstallation DVD may have issues with SecureBoot and UEFI. See here for details:
      http://dellwindowsreinstallationguide.com/download-microsoft-windows-and-office/download-microsoft-windows/download-windows-8-1-retail-and-oem-iso/

      If you are satisfied with Factory settings you may alternatively use Dell Backup and Recovery, see these new tutorial videos I made yesterday:
      http://dellwindowsreinstallationguide.com/dell-backup-and-recovery/

  3. I am having dell Inspiron N3010 laptop which was with win8 original and arch linux (dual boot). But due to some problem windows fail and I lost all data and windows Now I am installing Windows 8.1 on my LAPTOP (Custom installation ) but I get the following error message when the installation is on the “Installing updates” step of the installation:

    “Setup cannot continue due to a corrupted installation file. Contact the vendor of your Windows installation disc or your system administrator for assistance.”

      1. Did that and not solved the problem…The usb Flash Drive gives only to may laptop (dell) this error “corrupted installation file”. I have used the usb flash drive to install onto another laptop and installed win8.1 without any problem…The issue might be the hard drive?

  4. Hello and thanks for your guide. I have a Inspiron one 2330 and the hard drive crashed. I purchased a new 1TB hard drive but not sure if it’s either Windows 8 or Windows 8.1 installed on it. I have a Dell oem Windows 8.1 64 Bit DVD and was trying to install it but it’s asking for a product key which I don’t have. I have secure boot enabled and its still asking. Does this mean I should have a Dell Windows 8 DVD and not 8.1 in order to get past the product key. I really need help getting this fixed.
