Need Help with Grub

[Mark Phillips]

Is running fsck from knoppix any different than having Debian run fsck when
it boots up? I "touch /forcefsck" and then rebooted, and fsck ran on the
entire disk hda during the boot process. No errors or problems. So perhaps
just reinstalling the linux-image for that version would be the next step?

Thanks!

Mark
