I dont have ubuntu cd but I do have some old live cd: knoppix.
From there, I can run grub, grub-install, mount and such.
Lost partition is /dev/hda2 but can not be mounted:
mount: wrong fs type, bad superblock, or too much mounted drives [sic]
Why is that?
...I have no problem mounting /dev/hda1 (ntfs)
grub-install reports something like unable to write /boot/grub...
fdisk says nothing is wrong with the partition.
Once I boot linux from hard drive it should be easy to upgrade grub2 from there.
So, how do I set up old grub, not grub2?
