Just got nasty thing at the office computer.
Blank black screen with just movable cursor at the Win7 boot. Backups, restore don’t work. Wonder if that’s it.
Took me three days to get rid of it and restore sanity.
Sorry to hear about that. I run a Windows image in a partition on my Mac. If Windows crashes, I simply replace it with a fresh copy of a backed up image and restore data to that from backups. Painless. Best protection is to start with a fresh install, and restore data. Other guys periodically do fresh Windows installs, rather than repair a trashed OS.
