    Unhappy Grub2 Killed - Command Line Restarts On Any Command

    I've been attempting to configure a software raid1 using a pre existing Ubuntu 12.04 install by following the guide http://feeding.cloud.geek.nz/2011/03...-existing.html. I successfully completed step 4 but then couldn't get Ubuntu to boot into the degraded raid device. I read somewhere that you need to run the following command

    dpkg-reconfigure grub-pc

    from within the raid config, so as root, after step 4 I ran the following commands:

    mkdir /tmp/mntroot
    mount /dev/md0 /tmp/mntroot
    chroot /tmp/mntroot
    dpkg-reconfigure grub-pc

    this appeared to correctly update the grub.conf to the new raid setup.

    On boot I can bring up the grub boot list and by pressing 'e' I can see the correct commands. The kernel I'm trying to boot into now also gives the correct UUID for the raid drive 'md0'.

    Unfortunately if I try to go any further the system restarts.

    I have tried going to the grub command line by pressing 'c' at the grub menu. This succesfully brings up the command line:

    grub>

    Unfortunately if I type ANY command, including 'help' and press enter the system restarts.

    If anyone could help shed any light on this that would be greatly appreciated.

    I do not know RAID. But many systems also need help with video modes. I have to use nomodeset for my nVidia card.

    From the grub menu, e for edit remove quiet splash & add nomodeset.

    Sometimes other boot parameters may be required.
