Comment 6 for bug 60881

Thank Wladston, That does fix the problem yes, but the cause of the problem still has to be fixed so that other users of Ubuntu aren't deterred from using Ubuntu because it doesn't boot up.

The easiest way to start a system like this is to press "e" to edit the grub line, and change the /dev/hda1 to /dev/sda1, and then press "b" to boot the grub entry. That boots it OK, but the change isn't permanent. You can then edit /boot/grub/menu.lst to make the change permanent (as root)

My /boot/device.map contains just this line (which I haven't changed):
-------------------
(hd0) /dev/sda
------------------
That doesn't seem to work like that.

I will try get hold of Gutsy Ubuntu from my University soon. To test if it is fixed.
