I copied my unetbootin installation onto my Windows 7 machine, and formatted the drive and put something completely different on it. Then later I copied the installation it back on to the USB drive again.

Now when I try to boot from the USB drive, it states that the master boot record is missing. I originally created the USB stick with unetbootin. Is there any way to restore the master boot record, or get back the files I had stored in my home directory on the USB drive?

P.S. I'm not sure if this belongs on SU or "Ask Ubuntu", please take a approiate action.

Well here's a way of getting the files back at… (forgot I asked that) might as well leave the question here just incase someone knows how. – leeand00 Mar 14 '12 at 23:19

I think your various options are in Grub2: Reinstalling GRUB2 at the Ubuntu Documentation site. (...regardless that the difficulty involves your USB stick not your hard disk or SSD.)
