I have a Mac that runs macOS High Sierra, and a Boot Camp with Windows 10 that used to be running and up to date. But now, when I try to open Windows environment, I have got a blue screen with a
KMODE_EXCEPTION_NOT_HANDLED error message straight after I enter my Windows password. How can I get past this error message and open Windows, with or without reinstallation, whatever is doable/easier.
I have tried to use the Boot Camp assistant (under OS X), but I get an error message
The startup disk cannot be partitioned or restored to a single partition.
I have checked my partition and the possible issue is that I have an additional, 3rd partition disk, called "Windows recovery". I am unable to remove it even in OS X recovery mode ("-" is greyed).
I have tried to run
sudo gpt -r show disk0 as per Cannot delete partition (minus greyed out) - non-encrypted, no core storage but I get an error message
gpt show: unable to open device 'disk0': Operation not permitted even though I am currently using an admin account.
