---------------------------------Boot Master Boot Record (Help) -----------

This option boots whatever is in the Master Boot Record
of your 1st hard disk or 2nd hard disk or 3rd hard disk . . .

If you are lazy and don't want to reboot, it may be used 
to see how your PC boots from your 1st hard disk.

Also, it may be useful where your BIOS does not support booting
from the second of your hard disks.
