I've run into this same problem after converting root to ext4 after a Lucid upgrade. As soon as any files used by grub (kernels, stage1, etc) get converted to extents, grub fails.
Running grub-install from a Lucid livecd CD did not help: mount -t ext4 /dev/sda2 /mnt grub-install --root-directory=/mnt /dev/sda What seems to have fixed it was to boot from a Lucid livecd and do the following: mount -t ext4 /dev/sda2 /mnt mount --bind /dev /mnt/dev mount --bind /proc /mnt/proc chroot /mnt grub-install /dev/sda The 'rootfstype=ext4' kernel option does not seem to be necessary. Upgrading to grub2 is not an option for me yet because of Bug #392158. -- Patched grub will not boot from EXT4 partition https://bugs.launchpad.net/bugs/316872 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
