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?
