    Dual boot with 12.10 and Windows XP - even after boot-repair

    Hello,
    I installed Ubuntu 12.10 on an old Sony Vaio with Windows XP and ran into boot-up problem.

    I ran boot-repair after booting in live-cd mode and got:
    http://paste.ubuntu.com/1420128/

    After choosing repair option, boot-repair said the partition table has been fixed:
    http://paste.ubuntu.com/1420130/

    I boot again and the screen still shows only
    "error: no such partition
    grub rescue>"

    Could some one please advise what to do next? (I've already tried re-installing 12.10 once).

    Thanks in advance.

    Welcome to the forums.

    I would try boot repair again. This does not look quite right as it has both partition 1 and partition 6. Not sure if just an issue with boot script or your install of grub.

    Grub2 (v2.00) is installed in the MBR of /dev/sda and looks at sector 1 of
    the same hard drive for core.img. core.img is at this location and looks
    in partition 1 for (,msdos6)/boot/grub.

    If that does not work, you can manually reinstall grub.

    sudo mount /dev/sda6 /mnt
    sudo grub-install --root-directory=/mnt/ /dev/sda
    # The above command should work but they now suggest this command for grub 1.99 with Natty 11.04 or later - uses boot not root.:
    sudo grub-install --boot-directory=/mnt/boot /dev/sda


    You can also try manual boot:

    A good utility I have used in the past when this happened was Super Grub. It will fix MBR and many other things. Give it a try instead of messing with repair discs. http://www.supergrubdisc.org/ I personally prefer to use the original Super Grub, it isn't as advanced but seems more user friendly and effective. Rescatux is also a good tool to have on-hand, but is a much larger download
