Not sure of a more appropriate Stack Exchange website, but I have a really urgent problem that needs fixing, as I am leaving to China soon.
Last night my computer shut down abruptly, and upon restart I found that there was a corrupt user profile, so it logged me in as a temporary profile. I attempted to fix the problem by first creating a restore point and then using the Wise Registry Cleaner to revert to registry from a couple of months ago.
After logging out and restarting I cannot log back in. I've used Ubuntu via USB to replace the
Utilman.exe file in
System32 with the
cmd.exe binary so I can open that without logging on, but that's all the progress I've made. Both my main account stopped working, and my admin account disappeared entirely.
Right now, I want to boot up in safe mode or log into an admin account to do the system restore, but all I have is a command prompt with the
whoami command returning
nt authority\system. I do not have any installation disk or Windows 8 Recovery Media.
Upon attempting to run
msconfig at the command line and trying to save settings, comes up with a message something like "system configuration cannot save the original boot configuration".
If I try to do a system restore from command line, the restore point I made before using the registry back up from the Wise program is missing, and instead is a default restore point from this afternoon made by the system.
Thanks for your help!
