Screwed up MBR

So I was experimenting trying to get grub on a flash drive from ubuntu 8.10 when I accidentally ran:

install-mbr /dev/sda

instead of on /dev/sdb. Now when I boot up all I get is a 'prompt' that reads 'MBR' initially and then changes to 'MBR: FA:' a few seconds later. Does anyone know how I can restore the original boot record? Grub seems to be fine and isn't really the problem here - just the master boot record needs to be pointed in the right direction. Anyways if I can't get it I'll probably reinstall. Thanks in advance.

Never mind - I guess I just thought about it wrong. Never really thought that grub was part of the master boot record; I imagined it was the thing that was booted by the boot record. A simple '# grub-install --root-directory=/media/disk /dev/sda' fixed the problem. I thought It was just the MBR that changed....
