Warning, this is a bit long and rather technical. I made several attempts at Windows 11 upgrade & installation.
I have been running Windows 10 Pro for many years on a custom built desktop PC.
I downloaded the latest Win11 version from Microsoft and flashed it to a USB drive.
- first upgrade attempt.
a) I ran the installer. It told me the computer did not support Windows 11. I knew it should.
b) I rebooted and reset all the BIOS settings to defaults.
c) I was then able to run the installer, and the upgrade was seemingly successful.
d) Unfortunately, when I tried to start Virtualbox, which was previously installed, it told me that virtualization was disabled. This is because I had reset the BIOS settings earlier, and virtualization is disabled by default.
e) I rebooted and enabled AMD SVM in the BIOS. Unfortunately, after that, Windows 11 went into a never-ending reboot loop.
f) I disabled SVM once again, and was able to boot back into Windows 11.
g) I saved a backup of the initial upgrade attempt using Acronis True Image.
- fresh install attempt
a) I cleared the boot drive using DISKPART.
b) I used my original BIOS settings, which have virtualization (AMD SVM) enabled
c) I did an install without internet (NIC disabled in BIOS) and with local account (OOBE\BYPASSNRO) to make sure no updates/drivers would run.
d) the clean install booted OK
Of course, it's missing at least 17 drivers. And I may be underestimating that number.
e) I made a disk backup of this fresh install using Acronis
- second upgrade attempt
a) I restored the original Win10 installation using Acronis
b) I used my original BIOS settings, which included virtualization enabled, but added Trusted computing also
c) I booted back to Win10, ran the Win10 upgrade from USB again .
d) after the first reboot, it crashed, and rebooted once more.
e) it then reverted to Windows 10
f) Once it booted back to Windows 10, I got the following pop-up :
Is there any way to get more information about what failed than just this error code ?

There is likely some sort of driver currently installed under Win10 that Win11 doesn't like after the upgrade. Is there any way to tell which one ?
Trial and error is not really an option, given that there is so much hardware. There are some software drivers as well.
I really don't want to use the fresh install since I have a lot of customization done under Win10. I only did the fresh install to try to troubleshoot the issue.
