Let's install Windows 11 on incompatible hardware

inwell · Sunday at 4:33 AM

hello,

I was trying to upgrade my Windows 10 (unsupported hardware laptop) and tried different registry edit methods to bypass TPM 2.0 and Secure Boot requirements checking. Still I get the same error msg. The PC Must Support Secure Boot.

Any Idea why the registry edit workaround not working for secure boot ?
The registry edit workaround for TPM 2.0 and CPU Check worked.

Note: I do not want to use the RUFUS method/ bootable usb method as I wish to retain all my data and most of the apps/sw installed on Windows10.

PC:
Edition Windows 10 Pro
Version 22H2
Installed on ‎2/‎24/‎2022
OS build 19045.3930
Processor Intel(R) Core(TM) i3 CPU M 330 @ 2.13GHz 2.13 GHz
Installed RAM 4.00 GB (3.80 GB usable)
System type 64-bit operating system, x64-based processor

It's too bad you didn't write down which workarounds you tried. Have you tried this one?


Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup]
"AllowUpgradesWithUnsupportedTPMOrCPU"=dword:00000001

Sorry for that...
I have tried that registry key... also i have tried other 2 reg key options
HKEY_LOCAL_MACHINE\SYSTEM\Setup\LabConfig
BypassTPMCheck → Set to 1.
BypassSecureBootCheck → Set to 1.

Sorry, didn't work. Upgrade could not proceed and halted at Secure Boot Check.

I have these registry fixes in a .bat file, which I run as an administrator before starting an upgrade.

Batch:

reg.exe delete "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\CompatMarkers" /f
reg.exe delete "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Shared" /f
reg.exe add "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\HwReqChk" /f /v HwReqChkVars /t REG_MULTI_SZ /s , /d "SQ_SecureBootCapable=TRUE,SQ_SecureBootEnabled=TRUE,SQ_TpmVersion=2,SQ_RamMB=8192,"
reg.exe add "HKLM\SYSTEM\Setup\MoSetup" /f /v AllowUpgradesWithUnsupportedTPMOrCPU /t REG_DWORD /d 1
pause

These same fixes can be seen as Option Three in this tutorial.

Bypass Windows 11 System Requirements on Unsupported PC

This tutorial will show you how to bypass the Windows 11 CPU, RAM, Secure Boot, and TPM 2.0 system requirements allowing you to clean install or upgrade to Windows 11 on a unsupported PC that doesn't meet these requirements. Installing Windows 11 on a device that does not meet Windows 11...

the least invasive method to disable both clean installation and online upgrade checks.

Need an authoritative answer - what still works for UPGRADE installation of Win 11 24H2?

OK The iso route is the problem because often doing an upgrade via the setup.exe fails and you are left with an unbootable system. The safest way is to again Image your current system, save the drivers etc, create a Virtual machine and restore your OS to a VM. While using the VM the video and...

This is an extremely easy way to perform an UPGRADE installation on unsupported hardware:

You can use a Windows ISO image, DVD, thumb drive, HDD or SSD with the Windows files on it, etc. for this procedure. Make that media available to the system you wish to upgrade and note the drive letter. Open a command prompt and change to the folder where your Windows installation files are located.

As an example, suppose you have a Windows 24H2 ISO image and you mount it at D:. Open a command prompt (may need to be elevated, I do not recall), go to D:, then run these commands:

CD \sources
setupprep /product server

That is all!

NOTE: Do not let the reference to "server" worry you. You are not installing a server product

Hello,
I have tried this option previously.. but problem I faced is the option to Keep Settings and Apps is not available (radio button grayed out/disabled) Only Fresh Install and Keep Files are the two options available. (Any idea why the first option not available? )

The reason you're getting that option greyed out, I believe, is that the language that you already have set for your windows 10 OS isn't the same as the ISO image that you are trying to install. Because they are not the same, some options are not available.

As an example: I have my language set to English UK. If I tried to upgrade to Windows 11 using an ISO that is set to English US, the option to keep settings and apps would be greyed out. I would need to download Windows 11 ISO (English - International). The option to keep setting and apps would now be available.

This is my understanding, unless I have the installation procedure wrapped around my neck!

I think it has to match the original language of the installation.

HKLM\SYSTEM\CurrentControlSet\Control\Nls\Language\InstallLanguage

the hex language code 0409

at cmd prompt:
reg query HKLM\SYSTEM\CurrentControlSet\Control\Nls\Language /v InstallLanguage

I have current Windows 10 installed in English (US) Registry HEX CODE 0409 and the downloaded ISO is English International. Still I am not getting the option to retain Settings and Apps

That 'English International' ISO is Hex code 0809, en-GB. The ISO you need to use is the en-US one, that is just named as 'English'.

The "server" method works to bypass compatibility check, but the SSE4.2 requirement remains. If you have an older CPU without SSE4.2 support, go for 23H2. Also I have discovered that if you keep the unsupported computer connected to the internet, the first stage will reach up to 70-75% and then fail. So to be on the safe side, always disconnected from the internet until the upgrade to 23H2 or 24H2 is complete. Older versions didn't have this extra requirement.

This SSE 4.2 lacking will halt the 24h2 installation or installation will succeed and booting will fail...?

I tested for that here: Windows 11 24H2 has un-bypassable hardware requirements... - post #282

I'm doing a clean install now on an old laptop without SSE4.2....

First issue was that it couldn't even boot from the standard 24H2 install USB made by the MCT. It gets as far as the Windows logo, then reboots before it even starts the spinning 'loading up' circle.

Second attempt was with my hybrid 23H2/24H2 USB. That at least copied all the files, set them up and got to the first reboot. Same issue, it shows the logo, but then reboots before the circles appear....

Well you can fool Windows 11 23H2 Setup (or Windows 10 Setup) to install Windows 11 24H2 by replacing the file install.wim (or install.esd) with that from Windows 11 24H2 ISO, but at first restart the whole system will hang at the boot logo without the spinning curves. I had tried it on my test laptop (see 1st system specs), that doesn't support SSE4.2 Fortunately I had cloned my SSD first, so I just cloned 23H2 back and I can keep using it without doing a clean installation of 23H2 (not possible to recover once 24H2 has been installed and doesn't boot). So, yes you can install it, but not run it on systems without SSE4.2

PS: Similarly I tried to install Windows 11 (64-bit) on my HP Stream 7 tablet (UEFI firmware can boot to 32-bit only) using a hybrid Windows 10 32-bit and Windows 11 23H2 USB flash drive. Upon restart it could not boot because the Windows 11 bootloader is 64-bit and the tablet UEFI firmware is locked by HP to boot only in UEFI 32-bit mode :-(
