@boots Oh man I did that once.
I also once installed the windows mbr over grub once. I don't remember how I fixed EITHER ONE.
@boots tell them to google TuxPE, it's a vista install you can put on a usb stick
(the second person had managed to install grub over the windows mbr and didn't have a windows boot disc so they couldn't repair their mbr)
