I suspect this bug (or one very like it) is what just bit me on the upgrade from Kubuntu 10.10 64-bit to 11.04. It may not be exactly the same though, since in my case the upgrade didn't get confused by multiple valid installs - it just plain picked the wrong drive.
Post-install, the reboot brought up a grub prompt with an "ls /" that listed the contents of an old hard drive I had in the machine with assorted remnants of a previous install's "/usr" directory. For some reason, the upgrade process had decided to nominate /dev/sdc1 as the root of the machine, even though that directory contained no /boot and no /etc. The *actual* root directory (on /dev/sda1) was ignored. I'm currently still tinkering to get back to a bootable system - I suspect missed some references to the incorrect root partition in my first attempt. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/551790 Title: lucid update-grub wrong root=UUID= -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
