I can't access system restore, says 'The precedure entry point RtlIsThreadWithinLoaderCallout could not be located in the dynamic link library ntdll.dll.'
And when I try rebooting it loads to a black screen saying that ''windows could not start up properly and could be due to a recent hardware or software installation.'' there are several options including going into safe mode, last known config, start windows normally, etc. however, when i click on any one of these options, it brings me back to the same screen.
I really need help!
