Feature request: MBR backup

[wobble]

Hello everyone, 

I'd like to propose a backup-mechanism for GRUB2. 
On installation the old MBR could easily be stored in the partition hosting 
the stage2. 
That would allow for a clean self-destruction of GRUB2 as it could simply 
overwrite its own MBR-data if required. 

I guess many people install grub to play a little with linux/fbsd/etc and 
afterwards have a messed-up MBR and they want their Windows back. Such a 
feature would prevent a lot of support-requests I believe.



Cheers

Jan
