UPDATE: Removed the third method. It is unnecessary because there can be problems with it and the second method works with any Windows 11 build.

Hello, I have a MBP (MacBook Pro 16,2) installed with Windows 11 only, and I tried to upgrade from 22523 to 22526, but a few hours later it hung on a black screen. It was stuck on this screen and I left it for 5 hours and was still stuck on this screen. I am unable to boot into internet recovery as I deleted Mac OS off the machine. I tried making a USB, and tried booting it on the Mac, but it redirected me to the internet recovery screen. I tried booting into internet recovery, but got the -2002F error. I read that this is because the T2 chip doesn’t allow booting from a USB unless some settings are changed. How can I restore the Mac? I might be able to use another Mac to use to restore the Mac, but is there a way I can restore it without using another Mac or going to the Apple store?

The closest I have gotten to doing that would be starting an upgrade from Windows 7 to Windows 8.0 (unmodified 8.0 ISO, setup running with the /noreboot flag), removing the Windows.NEW folder, deploying Vista in a new Windows.NEW folder, then rebooting, then it would boot into the first stage, then boot into Vista. It hangs on "Please wait while Windows sets up your computer...". If you want, you can try this yourself and try to troubleshoot more. But that's the best advice I can give you as of right now.

Hello, I have a Surface Pro 6 dual booted with Windows 11 and 8.1. I have gotten past the windeploy part of setup by deleting intelpep.sys, as it will give me a BSOD with the INTERNAL_POWER_ERROR message with the file on there, but on the first boot, it gives me the INACCESSIBLE_BOOT_DEVICE error. I have gotten Windows Server 2012 R2 on there, so it probably has to do with a driver that is being loaded. How can I fix this?

No, I have been trying to find a way to do so, but I haven't found one yet. And unlike 10 and 11, some programs on 7 will not work on Vista, without the extended kernel.

Tired of Windows 11? Want to go back to Windows 10 without having to move files (well, kinda)? Well this tutorial is for you! NOTE: This will involve deleting some partitions and modifying the registry. Back up your files as we will run into some errors. 1. You will need two ISOs: a Windows 10 1507 or 1511 ISO and a Windows 10 20H2+ ISO. You can get these ISOs via Windows ISO Downloader 2. Mount the Windows 10 1507/1511 ISO and copy all of the files into another folder. You must use a Windows 10 1507/1511 ISO, or else this will not work. 3. Mount the Windows 10 20H2+ ISO and go to sources and copy "install.wim". In order to follow the steps on the tutorial, you must use 20H2 or later, or else the steps will be different. However, we are still using the 1507/1511 setup. 4 Right click "setup.exe", then click "Troubleshoot compatibility" 5. Click on "Use recommended settings". This will set the compatibility to Windows 8. 6 Click on "Test program". It will give you a UAC prompt, click Yes. 7. Go through setup normally until reboot. We are tricking the 1507/1511 setup into thinking that this is an upgrade from Windows 8 to 10, but we are actually "upgrading" 11 to 10. 8. Your computer should reboot three times, getting past the getting ready screen. After that, on the next reboot Windows will present you with the "Preparing Automatic Repair" screen. This is normal, so let it get to the Windows Recovery screen. 9. Go to Troubleshoot > Advanced options > Command Prompt. We are going to disable WinRE, rebuild the boot files, delete a faulty driver (IntelPMT.sys), and skip OOBE. 10. Type in these commands: cd /d C: rd Recovery /s /q diskpart sel dis 0 lis par sel par 3 (the partition labeled Recovery) del par (override) sel par 1 (your boot partition) assign exit bcdboot C:\Windows /s W: (where your boot partition is) bootrec /fixmbr bootrec /fixboot regedit 11. Go to HKLM and click File > Load hive 12. Go to C:\Windows\system32\config and import "SYSTEM". Name the hive something other than "SYSTEM", like "SYS" 13. Go to HKLM\SYS\ControlSet001\Services. Scroll down until you see the key "IntelPMT". Right click and delete the key. 14. We will also bypass OOBE. In that same hive, go to the Setup key, and set both CMD Lines to cmd.exe, and set all values to 0. 15. Now unload your SYSTEM hive. Exit the Registry Editor, then reboot. 16. When you get to your desktop, you will see that your apps transferred, but not your files. Your files should still be there in the Windows 11 folder, located in C:\Windows.old\Users\(your user). Copy all of the files into your folder from your old folder. Most apps will work, but some may need to be reinstalled, such as Bluestacks. 17. You will notice that some apps will not work, like the Personalization shortcut on the right-click desktop menu will not work. This all can be fixed with a repair install of Windows 10 20H2+. To do this, repeat steps 1-7 or use the original 20H2+ ISO. This should fix the errors. You could technically continue downgrading all the way down to 8.1, by downgrading from 20H2+ to 1511 with a similar trick, then 1511 to 8.1 (but downgrading to those OSES are much more complicated).

Yes I know that is one way to do so, I have listed a similar method by taking the file from the Windows 10 ISO and using it with the Windows 11 ISO.

I have never heard of this. I guess it would be, but the first method I posted seems to be easy as well. I will update and add this to the first post, but first I need to test it out to see how it works so I can post steps on how to do it.

UPDATE: Added a third method.

I tried doing a clean install of 11 22523, and after trying to run the Windows 10 1511 setup, I get the same error.

Yes it is possible since they use the same bootloader. You could even install Vista rather than 10 because it uses the same bootloader. All you do is shrink your main Windows 11 partition, make a partition for Windows 10 LTS, then install it onto that partition you made. It will automatically set up the dual boot. Hope this helped.

Hello, I currently have a Macbook Pro dualbooted with Monterey and 11 22504 (installed via Windows 10 20H2 setup) via Bootcamp. I am trying to upgrade to 22518, but whenever I try to update via Settings (I have TPM check disabled with a tool), it gives me the error 0x80888002. I try to upgrade with the setup, but end up getting the error "Sorry, we're having trouble determining if your PC can run Windows 11. Please close Setup and try again.". I've tried to upgrade to a newer build by using an older Windows 10 setup and setting the setup compatibility to Windows 8, but it gives me the same error. How can I fix this? Should I redo the Bootcamp or is there another fix?

The reason why the CPU is being rejected is because the CPU doesn't have PrefetchW. Is there a utility to bypass this like there is to bypass PAE with Windows 8?

I tried that, used that same ISO. I didn’t do anything during boot, also tried pressing F5 > Standard PC and F7, but I still got a BSOD with 0x0000007B.

Ok I have had success with that in the past, so I will try it and post later with results.
