Windows 10 Update Stuck in Automatic Repair Loop
When updating my Windows 10 computer with 2020-12 Cumulative Update for Windows 10 Version 20H2 for x64-based Systems (KB4592438) on restart I get Preparing Automatic Repair which seems to do nothing.
After a few restarts I got dropped into EFI shell only and could not get into Windows

After many searches of people with this issue I was not looking forward to possibly having to do some involved recovery. Some searches took me down the path of making recovery media or doing a BIOS update but I didn't end up doing that but that led me to looking at BIOS settings.
Since I was ending up in the EFI shell googling around took me to this post:
The solution mentioned in the post was turn off fast boot in BIOS settings. I did that and now on restarting I could get back into windows and a few days later was able to install the update (with fast boot still off).
I realize this answer could be better but I don't remember exactly the steps I took but this was the gist of it and I wanted to share what turned out to be an extremely easy fix.
