The same issue I found while installing Xubuntu 11.04 and Kubuntu 11.04 from flash drive on external HDD. During installation the root is /dev/sdc1 (sda - internal HDD, sdb - LiveUSB - installation source) but while loading without LiveUSB the root became /dev/sdb1 and starting fails to the BusyBox.
If I change the kernel boot options in GRUB (pressing "e" in GRUB menu) I can load the system. The command update-grub makes the correct grub.cfg (with UUID root drive identification). After that the system is loading fine. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/384633 Title: Grub Installer uses device name instead of UUID, leading to unbootable system -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
