Today I tried turning on pc and run into a wall. After windows ends loading instead of user logging screen I get black screen with just mouse cursor.
Alt+ctrl+del doesn't work, trying to boot up safe mode ends the same, can't recover since windows can't see any recovery points.
I didn't install any new software before it happened except for windows installing some new updates.
Recently I had issues with windows updates causing shut downs and blue screens but nothing so serious I couldn't deal with it.
I've red couple of threads about similar problem and so far I found one that could fix the issue ( Windows 7 boots to black screen with cursor before login screen after - Microsoft Community
the only priblem is when I try to set full power to all users i get this message: "No mapping between account names and Security ID's was done." and at this point I'm just stuck or I'm just mistaken thinking it might help.
If there is a way to fix it ( No mapping between account names and Security ID's was done.) with cmd (since it's basically the only tool I have access to), or if there is totally different way to deal with it, I would be very gratefull for any help.
