My recurring problem across drives with 96%+ health is that sometimes they hang on shutdown. When the computer restarts the bios will say something along the lines of no bootable device or something adjacent to that. Luckily I've got multiple computers so I can look at those in diskpart (using recovery mode>cmd) and the volumes will be misnamed, so Windows is changing drive c to something else and assigning drive letters to the recovery and hidden partition which is not supposed to happen. After manually unassigning/reassigning letters to volumes you must set all non-c drives to be inactive, only C:\ is setup that way, then do this bcdboot command on C:\, outside of diskpart. Simply reassigning letters does not fix the problem, you would think the boot files (bcdboot) are still there but it's like the bios doesn't know they exist or something. There are probably thousands if not tens of thousands of computers out there suffering from this problem, and automatic startup repair cannot fix it.
