DF Marrow, I agree. It is related to another bug I've been looking at: Bug #108554 "update leaves bootloader unable to find root partition"
In your circumstances I suspect the unexpected "Dell Restore" primary partition *after* the Extended partition is part of the issue. The numbering may have got confused. Primary Partitions are numbered 1-4. Logical partitions in an Extended Partition are numbered 5-8, so the usual discoery order is: 1 Recovery/Utility 2 Windows 3 Extended 5 Ubuntu 6 Linux Swap In your case it'll be something like: 1 Utility 2 Windows 3 Extended 5 Ubuntu 6 Linux Swap 4 Restore The best way to solve it is to use UUIDs to identify each partition. You can discover them using: $ ls -l /dev/disk/by-uuid Add them to /boot/grub/menu.lst so you have something like this: ## ## Start Default Options ## ## default kernel options for automagic boot options # kopt=root=UUID=bb2c3a14-1588-4fb9-8411-71f114b568b4 ro ## default grub root device # groot=(hd0,4) ## ## End Default Options ## title Ubuntu Gutsy 64-bit, kernel 2.6.22-14-generic root (hd0,4) kernel /vmlinuz-2.6.22-14-generic root=UUID=bb2c3a14-1588-4fb9-8411-71f114b568b4 ro quiet splash initrd /initrd.img-2.6.22-14-generic quiet savedefault title Ubuntu Gutsy 64-bit, kernel 2.6.22-13-generic (recovery mode) root (hd0,4) kernel /vmlinuz-2.6.22-13-generic root=UUID=bb2c3a14-1588-4fb9-8411-71f114b568b4 ro single initrd /initrd.img-2.6.22-13-generic title Ubuntu, memtest86+ root (hd0,4) kernel /memtest86+.bin quiet ### END DEBIAN AUTOMAGIC KERNELS LIST # This is a divider, added to separate the menu items below from the Debian # ones. title Other operating systems: root # This entry automatically added by the Debian installer for a non-linux OS # on /dev/sda1 title Sony Windows Recovery Tool root (hd0,0) makeactive chainloader +1 # This entry automatically added by the Debian installer for a non-linux OS # on /dev/sda2 title Windows Vista Home Premium root (hd0,1) makeactive chainloader +1 ** This bug is no longer a duplicate of bug 8497 grub guessed BIOS disk order incorrectly -- Cannot boot UBUNTU after installing 7.10 gutsy https://bugs.launchpad.net/bugs/156476 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
