My root partition is on /dev/hda10. When I try to upgrade, it tries to mount the root partition on /dev/hda1 (which is normally the windows partition). On the text upgrade screen it then comes up with a list of errors and asks the user to reboot. On the graphical upgrade screen, it hangs saying it is trying to find the root linux partition.
