    Re: Portable Updatable Ubuntu on Flash Drive

    Hi sudodus,
    Strange error, if you refer to the partitions with UUID, it should work even if you swap the connections. Are you sure there is good electrical contact? Maybe you have to unplug and replug the disks again.
    Agreed, that is my understanding too. Because of the nature of my PC my main hard drive is SATA and the 2nd is IDE which is linked in with the IDE DVD/ROM drive as there is only one IDE input on the motherboard.

    It has happened before so the above slightly strange configuration may be the cause.

    Yup, that's more or less what I did, disconnecting the internal hard drives and all. The Flash Drive install went fine but on reconnecting my drives a UUID Drive reference cannot be found and I end up at the Grub Rescue prompt! I've managed to boot in using various Grub2 commands but have yet to figure out how to make the fix permanent - sudo update-grub doesn't do it. I'll try it with the second HDD disabled then maybe edit fstab.
    We'll see...
    Did you install using a flash drive? I wonder if it is looking for this.

    C.S.Cameron:
    Got it sorted, thanks.
    Once I disconnected my IDE PATA Hard Drive (2nd Drive) it booted from my main SATA Hard Drive.
    I checked my UUID Drive Nos with
    Code:
    sudo blkid
    and they matched those listed in /etc/fstab. I then ran
    Code:
    sudo update-grub
    in Terminal, reconnected my second driver and all is well.

    No idea why the confusion happened, though.
