Description of problem:
GRUB location must be selectable as either MBR or /. Currently overwrites MBR,
destroying user's boot manager.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Install a boot manager, such as BootItNG.
3.Restore the MBR to the original boot manager.
Actual Results: Anaconda rudely gives only the choice of overwriting the
3rd-party boot manager MBR or booting off floppy.
Expected Results: Anaconda must allow retention of the 3rd-party boot manager
by specifying an alternate location for GRUB, such as /.
Other distributions offer a choice of putting GRUB in the MBR, or in / allowing
3rd-party boot manager to retain control.
This is configurable from the advanced boot loader options screen
