Do you still have the issue with the other drive? If so, and you can get an elevated command prompt open, run the sfc /scannow command, let it finish, it can take a while.
Hopefully, it'll fix the errors if any. If it finds errors but can't fix, then,in the same elevated command prompt type DISM /Online /Cleanup-Image /RestoreHealth , let it run.
After that finishes, run the sfc/ scannow again and let it finish.
