    Failed to reinstall Grub

    Recently i just format and reinstall Windows XP on Drive C.
    Afterward i boot into Ubuntu Live CD and type below command:

    sudo grub
    grub> find /boot/grub/stage1 (hd0,5)
    grub> root (hd0,5)
    grub> setup (hd0)
    Checking if "/boot/grub/stage1" exists... yes
    Checking if "/boot/grub/stage2" exists... yes
    Checking if "/boot/grub/e2fs_stage1_5" exists... yes
    Running "embed /boot/grub/e2fs_stage1_5 (hd0)"... 16 sectors are embedded. succeeded
    Running "install /boot/grub/stage1 (hd0) (hd0)1+16 p (hd0,5)/boot/grub/stage2/boot/grub/menu.lst"... failed Error 12: Invalid


    But it failed in the last stage? Previously when i format and reinstall Windows XP on Drive C, if i follow above commands it can success reinstall the Grub. But this time it failed to reinstall the Grub. May i know what is my problem and how should i fix it?

    Check out SuperGrub. It has helped me in several such circumstances. Just google it, download it, and burn it to a cd. It might take a minute to figure out, but it works really well.

    Okay, so it looks like your ubuntu is on sda5. When you boot up, do you see a Grub booting menu?

    Code:
    cat /boot/grub/menu.lst
    boot_info_script | AMD64 Athlon X2 Dual-Core - nVidia Geforce 6150 SE - 4GB DDR3

    So is sda5 your Ubuntu partition I assume? If that is the case, you should be using (hd0,4) in Grub's World, not (hd0,5).

    I had just using SUPER GRUB to FIX the Grub loading problem. Afterward, in Windows XP I installed "Ext2IFS_1_11.exe" to grant access to Ubuntu installation partition. I navigate to \boot\grub\menu.lst, open up menu.lst and correct the information from:

    title Ubuntu 8.04, kernel 2.6.24-19-generic
    root (hd0,4)
    kernel /boot/vmlinuz-2.6.24-19-generic root=UUID=55a88a7e-1df4-4a44-bbbc-6fe536270423 ro quiet splash
    initrd /boot/initrd.img-2.6.24-19-generic
    quiet

    To:
    title Ubuntu 8.04, kernel 2.6.24-19-generic
    root (hd0,5)
    kernel /boot/vmlinuz-2.6.24-19-generic root=UUID=55a88a7e-1df4-4a44-bbbc-6fe536270423 ro quiet splash
    initrd /boot/initrd.img-2.6.24-19-generic
    quiet

    Now i finally able to boot into Ubuntu from the Grub loading screen!
