After I updated Debian to Wheezy whenever I boot my computer I get Grub boot error hd0 out of disk and then a prompt comes up with grub rescue>. So far I have been unable to find a solution by googleing. When I run grub-update on a live system I get bash: grub-update: command not found.

  • Not really as that person didn't have grub at all, whereas my problem is that I am getting a grub error. Thanks for showing me that though.

  • Nevertheless, read the answer, not the question. It is highly likely that reinstalling grub will fix your error. For example, in the answer I explain how to run update-grub (grub-update is now called update-grub). I don't know what that particular error means but attempting to reinstall grub is probably a good idea.

  • @qsylalyn no, terdon's answer is basically about reinstalling grub if it doesn't work. the question itself is not that relevant perhaps Mar 26, 2014 at 23:48
  • Thanks, how can I find where it is mounted?
