    Debian spoiled my partitions

    Hi!

    I've just installed Debian Squeeze along with Ubuntu 12.04 and I'm already having problems...

    Ubuntu won't start. While booting, it eventually stops and tells me that it is unable to mount /tmp. Same thing happens with the rest of partitions, except /home and / (which were not used on Debian installation). I checked Debian's fstab and it turns out that the UUID of the devices differ from those on Ubuntu's fstab.

    Has Debian changed my devices UUID? Can I just edit Ubuntu's fstab so the UUIDs are those on Debian's fstab?

    Thank you for your time.

    Yes, I think that Debian probably reformatted the partitions which would have changed their UUID. If that's the case, anything that was on them is gone.

    Yes, you should be able to use a live CD (or Debian) to edit and correct /etc/fstab on the Ubuntu root partition.

    You will be dependent on Debian's installation of GRUB. If you want to revert to Ubuntu's GRUB, the two commands in Ubuntu are:
    Code:
    sudo update-grub
    sudo grub-install /dev/sda
    but I would probably leave Debian's GRUB on there unless there is a reason to change again.

    Ok, just to be sure: it is safe to rewrite ubuntu's fstab UUIDs to the ones on Debian, right?

    Thank you very much.

    Not sure what that means. So here's the procedure I would use. It assumes that I know exactly what is on which partition already:

    Boot Debian or a live CD
    Use sudo blkid to get the current UUID of all partitions
    Mount the Ubuntu root partition at /mnt : sudo mount /dev/sdaX /mnt
    Edit /mnt/etc/fstab and edit it : sudo nano /mnt/etc/fstab
    Correct the UUIDs, save and reboot

    Out of interest, you could compare the Debian fstab with the blkid output, but I expect that they match so no surprises.

    Thanks, worked like a charm!
