    Unhappy Can't restore GRUB

    After installing Vista (downgraded from 7 RC), I booted into Ubuntu LiveCD to restore GRUB following the instruction on the Ubuntu documentation. I did what it said to do, but when I rebooted again it went straight into Windows. When I tried holding down the Esc key while booting as suggested in the docs, my system just restarts. And Windows bluescreened a few times while booting, but I'm not worried about that. I just need to get back into Ubuntu.

    Re: Can't restore GRUB

    If you have more than one hard drive, change the boot order in the Bios.

    If that did not cure your problem: Follow the instructions to run the boot info script and post the RESULTS.txt.

    Re: Can't restore GRUB

    => Windows is installed in the MBR of /dev/sda
    Boot sector info: Grub 0.97 is installed in the boot sector of sda2
    You installed Grub to the boot sector of the Ubuntu partition, instead to the MBR. To fix it, boot from the Ubuntu LiveCD (version 9.04 or older) open a terminal.

    Code:
    sudo grub
    and at the "grub>" prompt:

    Code:
    root (hd0,1)
    setup (hd0)
    quit
    Reboot and you should get the Grub menu and should be able to boot into Ubuntu and Vista from the Grub menu.

    Re: Can't restore GRUB

    Thanks, that works great. I was under the impression that GRUB was supposed to be installed on your Linux partition.
