    What is the error number? Does it happen before you see the grub menu, or after?

    As a (hopefully) easy fix, try reinstalling grub to the MBR from the live CD like this:

    See this about grub error 16:
    http://members.iinet.net.au/~herman546/p15.html#16
    TRy booting from the Ubuntu live CD, open a terminal, and run fsck to check the file system:
    Code:
    sudo fsck -f /dev/sdXY
    Replace XY with the drive and partition numbers for your Ubuntu root partition. For example, for me it would be:
    Code:
    sudo fsck -f /dev/sda2
    It looks like something is screwed up somewhere. I'm wondering if this is more than just a grub configuration problem. Anyway, try fsck from the live CD and reboot.
    Also, can you post your /boot/grub/menu.lst file.

    Let's get a better look at your setup & boot process. Boot the Ubuntu Live CD. Choose "try ubuntu without any changes", when the desktop loads come back here and use the link in my signature to download the Boot Info Script 0.32 to the desktop. Once on desktop open a terminal and run this command
    Code:
    sudo bash ~/Desktop/boot_info_script*.sh
    This will create a RESULTS.txt file on the desktop. Paste the entire contents of that file back here. Once pasted highlight all text and click the # sign on the toolbar to place code tags around the text.
    Multi-boot: Arch linux, Ubuntu 12.04, Windows 7 & Windows 8
