I think it should still prompt clearly for permission to splat the boot
record.  There could be an OS (or multiple OSs) on other disks which the
boot loader can reference.  Just because you have complete ownership of
*one* disk is not indicative of being able to take over the entire boot
record.  There are probably too many edge cases here to make a reliable
automated decision, hence the necessity of a question.
