OK, I can now boot the system. I fixed the menu.list to correspond to the
drives as they are installed today. However, I have now discovered that I
may have a bad spot on the drive.
My first two entries in menu.list:
title Debian GNU/Linux, kernel 2.6.26-2-686
root (hd0,4)
kernel /boot/vmlinuz-2.6.26-2-686 root=/dev/hda5 ro
initrd /boot/initrd.img-2.6.26-2-686
title Debian GNU/Linux, kernel 2.6.26-2-686 (recovery mode)
root (hd0,4)
kernel /boot/vmlinuz-2.6.26-2-686 root=/dev/hda5 ro single
initrd /boot/initrd.img-2.6.26-2-686
will not boot. I get the dreaded "Error 24 Attempt to access block outside
partition". But I can boot into the rest of the entries:
title Debian GNU/Linux, kernel 2.6.26-1-686
root (hd0,4)
kernel /boot/vmlinuz-2.6.26-1-686 root=/dev/hda5 ro
initrd /boot/initrd.img-2.6.26-1-686
title Debian GNU/Linux, kernel 2.6.26-1-686 (recovery mode)
root (hd0,4)
kernel /boot/vmlinuz-2.6.26-1-686 root=/dev/hda5 ro single
initrd /boot/initrd.img-2.6.26-1-686
and so on.
I forced a fsck on a reboot, and that I get the same error 24 when I try to
boo the first two entries in menu.lst, but I can still boot into the other
ones.
Should I apt-get reinstall linux-image-2.6.26-2-686 (assumption: the vmlinuz
file is corrupted), or do something else more basic to repair the drive
(assumption: there is bad sector)?
Thanks!
Mark
