Quoting Pascal Hambourg <pascal@plouf.fr.eu.org>:

After it asked me to remove the DVD so it could reboot, Grub loads and reports: error: no such diskBefore displaying the boot menu or after starting a boot entry ?I booted into rescue mode using DVD 1, went to a shell and ran: # fdisk -l /dev/sda boot .... System /dev/sda1 * Linux /dev/sda2 Extended /dev/sda5 Linux LVM I wanted to look at grub.cfg so I typed: # mount /dev/sda1 /mnt cd mnt/grub nano grub.cfg Everything looks fine. It does say: set root='(hd0,msdos1)'Does grub start a rescue shell ? If yes, what is the output of "ls" and what does "set" display about prefix= and root= variables ? -- To UNSUBSCRIBE, email to debian-user-REQUEST@lists.debian.org with a subject of "unsubscribe".

Hi Pascal, error: no such disk is before the boot menu. I am then dumped into grub rescue> grub rescue> ls returns a single blank line. grub rescue>set prefix=(hd0,msdos1)/boot/grub root=hd0,msdos1 grub rescue> help-grub@gnu.org is recommending: "device.map is irrelevant when booting although it could cause incorrect image to be generated. Best is to remove it, it is not needed by grub2 under normal conditions. Most likely you have old grub image on disk that refers to filesystem that is no more present. You need to reinstall grub from rescue CD. Boot with any live media, mount /dev/sda1 and run grub-install, like mount /dev/sda1 /mnt mount --bind /sys /mnt/sys mount --bind /proc /mnt/proc mount --bind /dev /mnt/dev chroot /mnt grub-install /dev/sda As I said better is to remove device.map before running grub-install May Debian has some specific instructions how to recover bootloader in which case you better ask them. Also above will make grub2 primary bootloader; if you dual-boot you may want to install grub on partition." I need to debianize those mount commands. Thanks for responding. Debian usually goes on quite smoothly. This is new for me. Chris
