Bug#549337: upgrade-from-grub-legacy, had to fsck in order to boot

[Moritz Möller]

We use ext3 - and yes, it was the superblock time. Pressing ctrl-d + reboot did the job, however, it happens every boot (boot - Ctrl-D+reboot - boot - works - goto 1).

This was with chainloading from grub1, after running upgrade-from-grub-legacy I wasn't able to boot at all, Error 16 or 17 if I remember correctly.
