This has been very frustrating. I'm pretty sure this happened a day or 2 after I used ccleaner's registry cleaner (yes I know I shouldn't have). My computer would start kind of lagging up and being slightly noisey. Then a blue screen appeared briefly with some wording before crashing. Now it just boots to a black screen with the blinking line in the top left. Sometimes when restarting it, I'd get an error about windows having a problem with a boot file
Things I've tried:
Downloaded the tool here to a flash drive: https://www.microsoft.com/en-us/software-download/windows10
- Did the Troubleshoot > reset this pc > keep my files but it says "the drive where windows is installed is locked. Unlock the drive and try again". I've done lots of research on unlocking it with some commands in the command prompt, tried again and was able to start the process. But it hung at 1% and failed. Haven't been able to get that fair again...
- System restore option says "to use system restore, you must specify which windows installation to restore. restart this computer, select an operating system, and then select system restore"
- Under troubleshoot > advanced options > command prompt ....the spot is x:\Sources>
Some kind of headway and help would be amazing. Thank you!
