You don't need Rufus. You start the Windows 11 installer, when the Setup is running press Shift + F10 to open the command prompt and then use regedit. But I don't post the details. Just search the web for the instructions.

Oh ok, im just not sure how to get to that point since I can never get the installer to start before the computer reboots.

Anyway, you can try to start an official Windows 11 installer on the Phenom and enter manually the bypass instructions. Maybe all works fine.

How do I do that? With Rufus? If so- I have rufus but am not sure how to bring up the menu for disabling/bypassing that stuff.
Also- thanks for all the help !

I used 'WinBootMate' to create my flash drive for the windows 11 install - it bypasses CPU / TPM / Secure boot check for creating windows.

The CPU check is used to ensure that the CPU has all necessary CPU instructions implemented to run Windows 11. When the check is disabled, it does not mean that the CPU is able to run Windows 11. When Windows 11 tries to use an instruction that is not available with this CPU then you get a system halt or reboot. We see the reboot.

AMD FX 8300, and it runs windows 11 just fine

The AMD FX 8300 was built 2011, the AMD Phenom 9950 was built 2007. The Phenom has not the same features as the newer CPU FX 8300. It looks like the FX 8300 has all that Windows 11 needs, or there was no invalid instruction call so far.


Look, you have always the reboot regardless how the modified installer is started on the Phenom. You have also a reboot when Windows 11 is already installed by another computer and then started on the Phenom.

Anyway, you can try to start an official Windows 11 installer on the Phenom and enter manually the bypass instructions. Maybe all works fine.

Well the CPU might be an issue, but im not so sure. I have windows 11 installed on another computer that has a CPU thats not on that list, it is an AMD FX 8300, and it runs windows 11 just fine. Also, I used 'WinBootMate' to create my flash drive for the windows 11 install - it bypasses CPU / TPM / Secure boot check for creating windows. I also have rufus but on that app I dont see how to disable that stuff when creating a flash drive. And i think WinBootMate is better.

This CPU is not supported for Windows 11 !

See https://learn.microsoft.com/en-us/windows-hardware/design/minimum/supported/windows-11-supported-amd-processors

Thank you Bazong. I think, this explains the reboot.

More infos and howto maybe bypass Win11 restrictions see here https://blog.silverpc.hu/2025/10/19/is-it-possible-to-install-windows-11-on-an-unsupported-amd-phenom-ii-processor/

For bypass restrictions you can try to make a Win11 USB installation stick with Rufus https://rufus.ie/en/

I really dont think RAM is the issue, it runs fine with windows 7. The computer has an ASUS M2A-MVP motherboard, 8 gigs of DDR2or3 ram, and an AMD phenom 9950 quad core CPU. I would think it would be able to run windows 11.

Maybe its not possible to run Windows 11 on that computer. I don't know. Enough RAM is installed? The RAM modules are fine?

Maybe the best solution is to put the hard drive into another computer and install Windows 11 without the features. Then put the hard drive back and see what happens.

Iv'e actually tried that. The hard drive Im trying to use i actually had just installed windows 11 on, on another computer that was only a few years newer than the one im trying to use. Out of curiosity I tried just booting off the HD when i first plugged it into the computer, it said attempting windows repair and then would just reboot. I just today tried plugging that hard drive back into the other computer where I ran the very first part of the windows 11 install, up to the point where it restarts the computer for the first time - I then put it back into the computer that I want to use, and then it just shows the windows 11 logo for 2-3 seconds and reboots.
