The MBR isn't all of the boot process anymore, generally additional code is in 
the sectors after the first sector. I have a disk imaging project, and gone to 
having it save a lot more than 1 sector with the MBR backup process. 
Generally, the first partition starts at 1M instead of the second track. 

Know that grub2 puts some extra code after the MBR and assume that 7 and 
above also do.
