    Mythbuntu 10.10 Grub Promt Boot Issue

    Ok, I've looked on this forum and alot of others and find some solutions but none seem to work for me.

    Fresh install of Mythbuntu 10.10, not from Windows and no dual boot, just straight up install.

    It boots to a Grub prompt. I can get the system to boot into Mythbuntu by using these commands:

    Code:
    linux (hd0,msdos1)/vmlinuz root=/dev/sda1 ro
    initrd (hd0,msdos1)/initrd.img
    boot
    It will boot to Mythbuntu (which I'm using now), but on reboot it will do the same thing, into the Grub prompt.

    I have followed some advise and ran these:
    Code:
    update-grub
    install-grub /dev/sda
    Both of which run with no issues, but do not fix the problem. I can deal with having to type the commands on restart, as I won't be doing it very often, but it is very annoying. Any ideas from all the gurus here? I'm just a recreational user.

    Thanks!

    We can't really tell the problem since we don't know what is in your grub.cfg menuentry.

    If you will run the boot info script from the following link and post the contents of the RESULTS.txt we can see what your boot files look like and give you some informed advice:

    Re: Mythbuntu 10.10 Grub Promt Boot Issue

    A3M0N,

    Thanks for posting. The files look correct. One issue may be the location of grub.cfg on the disk. It is well beyond the other grub files on the partition, so it's possible Grub2 isn't finding the grub.cfg file due to a BIOS limitation. BIOS's from a few years ago couldn't see past the 137 GB limit. Once the system boots, the OS can see everything but the BIOS can't.

    When booting, you can enter BIOS and check the drive size. If it shows 137GB or less you want to look for a setting to enable large drives or LBA. If you can't find such a setting you may need to update your BIOS.

    If neither or those is an option you may need to make a /boot partition within the first 137GB of the disk.

    Let us know what you find.

    Re: Mythbuntu 10.10 Grub Promt Boot Issue

    I was not on an upgrade. Had done an install of Ubuntu 10.10 only to my Durabook N15Ri-2.
    On return home this evening my password would not be accepted.
    Rebooted, got the Grub prompt too.
    I plan to post the grub cfg as listed in the previous posts on this subject. Would appreciate knowing what the next step to do is.
    I still have the Ubuntu 10.10 CD I set up for the install.
    And obviously from this I can get out to the Internet and e-mail in the demo version of the boot up.
    Sincerely,
    Gschultz

    There is no bootable MS on this machine that I've seen.
    I'd like to restore to where I was with Ubuntu until this evening. It was running fine and had done an update manager upload last evening. I would appreciate some help with it.

    Re: Mythbuntu 10.10 Grub Promt Boot Issue

    gschultz545,

    Welcome to the Ubuntu forums.

    I don't see any glaring errors with your boot information, and I don't know if whatever was causing your password issue is also responsible for the grub prompt.

    In cases where the RESULTS.txt appears normal, I refer people to the following guide. It will have you remove and reinstall Grub2 to ensure your boot files are not corrupted. If the system still does not boot, this procedure should rule out Grub as the guilty party.
