Windows 10: Is it possible to restore my Windows 10 system after the Win 11 rollback procedure fails?

I had a stable, working Windows 10 Pro installation on my self-built desktop PC. I decided to update to Win11 and, shame on me, did not mirror my system drive first.The upgrade to 11 went smoothly except that I couldn't get networking to work. After a couple of hours of fruitless reading and tinkering, I decided to use the Help Tool to roll back to Win 10.That process seemed to be working OK, but then it failed during a reboot. Now, UEFI doesn't recognize a valid installation of either version of Windows on my system drive. Booting to Win 10 install media on a thumb drive doesn't help - af

I'm trying to rollback my windows 11 back to windows 10, and during the restoring process, my PC suddenly got a BSOD with the code System Service Exception, and the file listed was Ntfs.sys, now I'm stuck in this restoring loop and I can't access the desktop, is there any possible way to fix this?

 

Rollback Rx Home & Restore Point System (0x8004231F)

Thanks.

Rollback RX say System Restore isn't disabled when Rollback RX is installed, but that there 'may be compatibility issues'.

Also that SR is redundant when Rollback RX is in use, which is self evident.

It's common experience that System restore frequently fails to succeed in restoring, so it would be better to rely on somehting that does.

I would also be careful to check the implications of using Rollback RX when applying a feature upgrade or an in-place upgrade repair install (same procedure).
