Help! I recently upgraded to Ubuntu Natty Narwhal and it broke my Grub boot loader. I have logical volumes btw. I've been trying to repair it but when I repaired it I got an error "the symbol grub xputs not found" and then I get the grub rescue prompt. I have the feeling that I am not going to be able to boot into my machine without a fresh install. I used rsnapshot to backup my servers. Does anyone have any recommendations on restoring these backups. There are lots of tutorials regarding backing up but very little on restoring.
