Failed to install NTLDR/BOOTMGR

Not too great with computers and dont understand much but my operating drive was corrupted so i tried to do an automated repair on windows 8. It started and stopped at "Failed to install NTLDR/BOOTMGR to selected device! Check logs for more details" I have no clue what to do now. Help would be greatly appreciated.
P.S when i go to select my the drive under the active column it says no instead of yes idk if that means anything
