Small anecdote, fdisk /mbr once saved my database class project at the university, thanks to it I was able to rescue a PC that everyone though it was dead and thus was able to secure a terminal for our set of teams.

Alternatively, we would have had to wait endlessly for a free one, while we had a fixed deadline regardless of the students assigned to the class, and no the software wasn't available elsewhere beyond our computer lab.
