    Question Can't boot BT after installation of Ubuntu

    After installation of Ubuntu I cannot boot to backtrack anymore.

    This is my fdisk printout:

    Code:
    Disk /dev/sda: 320.0 GB, 320072933376 bytes
    255 heads, 63 sectors/track, 38913 cylinders
    Units = cylinders of 16065 * 512 = 8225280 bytes
    Disk identifier: 0x0a53d359
    
       Device Boot      Start         End      Blocks   Id  System
    /dev/sda1   *           1        2089    16779861    7  HPFS/NTFS

    /dev/sda9           38338       38913     4626688+  bb  Boot Wizard hidden   ///BACKTRACK'S ROOT

    and menu.lst
    Code:
    title		Win7

    savedefault

    quiet
    
    title 		BT4
    root (hd0,7)
    kernel /boot/vmlinuz ro root=/dev/sda8
    boot
    What am I doing wrong?

    The filesystem type has to be linux and linux swap/solaris. So change those boot wizard hidden entries into such same entries as shown in sda6/sda7 for sda8/sda9

    Hmm, I am not sure what did you just say.
    Can you rephrase it?

    If sda8 is Boot and sda9 is Root, should I set both to 83?

    Is /dev/sda6 where you installed Backtrack? If yes, then try:

    title BT4
    rootnoverify (hd0,5)
    kernel /boot/vmlinuz vga=791 root=/dev/sda6 ro
    boot
    savedefault

    As you can see from the code I pased, I installed BT on sda8 (boot) and sda9 (root). sda6 is ubuntu.

    I tried your script modifying it for hd0,7 and sda8 but I still get Error 15 in Grub.

    I spent a lot of time trying to install Backtrack on my disk and now I cannot use it. Can someone help me fix it?
