A Repair Install can take hours depending upon how much crap it has to back up before reinstalling, then replace it all while trying to screen out bad settings affecting System files.
This is one of the most complex software operations in existence. It may ponder a questionable setting for an interminable time trying to decide if it should be reimported. If this cannot be resolved it may abort.
Even if it works perfectly, it will never match a Clean Reinstall where you start fresh with no chance of reimporting problems. But it often solves intractable problems like Updates failure, damaged System files (often from those same sketchy settings) and boot issue since it reinstalls the OS.
Thanks for this clarifying post, Greg.
