    8.04 to 10.04 upgrade Alert! /dev/disk/by-uuid does not exist

    tried to upgrade from 8.04 to 10.04 and I get this error. I restored back to a snapshot after the 10.04 was installed upgraded to 12.04 and still get this error


    I have attached a screen shot. Anyone have any clues why this happened and how to fix?

    It looks like the UUID of /dev/sda1 has changed for some reason. you should be able to use a Live CD to chroot the partition, then check what the UUID of the partition is in /dev/disks/by-uuid. Use the following commands to chroot the partition after booting from a Live CD.

    Code:
    sudo mount /dev/sda1 /mnt
    sudo mount -o bind /dev /mnt/dev
    sudo mount -o bind /sys /mnt/sys
    sudo mount -o bind /proc /mnt/proc
    sudo chroot /mnt

    all those commands ran perfect. I got the UUID, how do I change it? I rebooted and it is still the wrong UUID

    I tried running tune2fs and no go.

    After I got the UUID I just had to edit the menu.lst with the proper UUID. Saved and got a viminfo cannot write. Then I ran update-grub and now it's booting! Can anyone explain why this broke to begin with?


    The problem I face now is my login doesn't work. says login and I try root and my username even and it just blinks and goes to a blank.
