No luck for me with this fix. I did just update the BIOS and all the drivers but one. Still no luck on 20H2 installing, but it does now auto-revert when 20H2 fails to install vs just going to blue screen and a manual effort to go to 1909 version of Windows. My NVIDIA driver will not update without giving me the blue screen; maybe there is some relation...?
I have reinstalled windows 3 times from scratch from the original windows version through every update. Works fine until getting to 20H2.
