Ok, I noticed that most people who are having Grub Error 17 issues are dual booting. I on the other hand have a single Sarge install. Was running a TAR backup which froze. I did a hard boot on the system, and now am getting the Error 17 while GRUB loads. I have Knoppix loaded and am unsure how to resolve this issue. This is a testing machine, but if this ever happens again, I would like to know how to resolve this. Seems like just letting grub know where the hard disks are, but how to do that... ?
