Did a test on a system.
Copied the mbr sector.
blanked out the first 1M of disk.
Copied back the mbr sector
did a grub2-install.
copied the first 1M.

Mbr being the first sector with core.img after that.
Core.img went from byte 200 to 7D9C, but other code continued 
to F9FF before it got to the all zeroed out code.
