I manage multiple computers running Windows 10 Pro 64-bit with the latest Current Branch and recently had multiple computers randomly startup with this BSOD: Inaccessible Boot Device.
I have tried everything:
Which recommends deleting registry keys and install packages, though no pending installs could be found
SFC /SCANNOW - No corruption found
CHKDSK /R - Some minor issues corrected
BOOTREC - Scan OS shows 0 windows installations
FIXBOOT - Successful, but this tool finally made the entire process fail without being able to get to the recovery environment, just boots to the legacy screen and shows options for safe mode, but those fail too.
I am at my wits end, because I find thousands of websites and desperate users and admins, but the only fix that works is to clean install. I can't clean install the whole company. This is insane, there has to be a better known cause / fix out there...
