    Default Boot Failure no such partition grub rescue

    Hello

    Here's my situation.

    I had dual boot vista and Backtrack5-r1. After reinstallation of Vista. I got error saying:

    GRUB loading.
    error: no such partition
    grub rescue> _


    even though I have completely reformated the HDD and installed a fresh Vista.
    help command is unknown, nor /?, but ls command shows:

    grub rescue> ls
    (hd0)(hd0,2)(hd0,1)
    grub rescue>


    I have googled and tried a few with no success, it keep showing me "unknown command"
    I have a bootable BT on USB.
    Any idea?

    Thank you.

    I have a similar story,
    Windows7 installed in the first partition 15Gb or so, second partition for documents. During the BT5R1 install re sized the documents partition by 16Gb, then after install the grub rescue> prompts
    I try set root=(hd0,0 or 1 or2) but what to do next?
    initrd,kernel and many other commands says unknown command,

    grub rescue> ls
    (hd0)(hd0,2)(hd0,1)

    grub rescue>set
    prefix=(hd0,5)/boot/grub
    root=hd0,5

    I am using IBM Thinkpad T30 laptop. HD is 160GB. 1GB ram.

    Been trying to use
    set prefix=(hd0,0/1/2)
    set root=(hd0,0/1/2)
    then insmod normal but in neither of the 3 it worked.
    Im kind of in the dark here, what to do?

    Booted from the BT5R1 dvd and gone to install again to see my partition table, it goes
    /dev/sda
    /dev/sda1 ntfs
    /dev/sda2 ntfs
    /dev/sda5 ext4
    /dev/sda6 swap

    If you have an older computer it's possible the BIOS cannot see your GRUB 2 files if they reside past the BIOS limitations (generally 33 GB on very old computers and 137 GB on slightly newer computers). If this is the case the boot will fail and an error: no such partition message will be displayed.
    How to know if my ThinkPadT30 has a limitation such as this?

    Well, you do this:

    grub rescue>
    set prefix=(hd0,5)/boot/grub
    set root=(hd0,5)
    insmod normal
    normal

    now Grub menu might show up

    Thank you everyone!

    Here's how I resolved it:
    Vista
    1. Boot from Win CD,
    2. Set date and time, etc...
    3. Choose repair instead of install,
    4. Choose cmd, type the commands:


    bootrec.exe /fixmbr

    Restart computer.

    I have also noticed an advance option in the first steps of BT installation that let you choose whether you want to install bootloader. Pay attention and you'll find it under your nose. I think it's the same bootloader that changed the default Win bootloader for me.
