I would assume I can just reverse the input file (if) and output file
(of) statements to restore?
I had used dd to take a backup of my FC5 setup before a "clean
install" upgrade to FC6. I took the MBR, / & /boot partitions. I left
/home intact. Fortnately FC6 didn't cause any problems, and I did not
have to restore. But I guess it should work. But a second opinion
about restore would be needed.
Alternatively, you can use the dd'ed MBR file to call grub from within
boot.ini of windows. I have done that before on dual boot systems
who's grub got overwritten. It's a less used alternative (provided you
have a backup of the MBR) to booting into rescue and doing a
grub-install.
I've been using the second method for some time now. It works okay, but
is restrictive as NTLoader is not very sophisticated.
This can't be used with Vista, as Vista changes how it works.
Still, I did find that going back to Grub works fine, and you can boot,
XP, Vista and of course Linux.
I just wondered if 512bytes was enough to get the whole MBR? If it is,
then restore should work, no probs.
