I tried to upgrade my PC in 3 different ways
- Windows Update shows my system does not meet W11 requirements but the PC Health Check says it does
- Mounted ISO from file on M.2 C: drive and tried to upgrade - would run but later fail to reboot with INACCESSIBLE BOOT DEVICE and rollback
- Made bootable USB from the same ISO and tried to upgrade - fails immediately (not sure if it is supposed to be used in upgrade)
EDIT:
upgraded ASUS BIOS to latest v 4021, Aug 21
as suggested in another thread (I pass the health check but the update installer says my PC doesn't meet the requirements)
Checked my disks they are GPT
Also have ran WhyNotWin11 and it shows all clear.
Any ideas how to get out of this?
