I experienced this same problem after an apt-get dist-upgrade to move from Dapper to Edgy on my laptop. Examining the boot messages showed that the wrong partitions were being mounted (or at least attempted). I was able to boot to a liveCD and edit the menu.lst to solve the problem, menu.lst had the wrong UUID listed. After resolving that issue I am able to boot to my laptop without problem.
My laptop's partitioning scheme is a bit complicated for reasons I won't go into, so that may have confused the upgrade engine. I have /dev/hda6 as my /home/ partition and /dev/hda7 as the / partition. I would guess that perhaps the upgrade program looked for the first available Linux partition and assumed that was the right one to boot. In this case that was not the right answer. If that's not the case I have no idea why it decided to boot to hda6 rather than 7. -- Kernel 2.6.17-7-generic fails to boot, I get the BusyBox instead https://launchpad.net/bugs/59792 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
