    [SOLVED] ubuntu grub problem

    I have installed windows on my system in 20 GB partition and ubuntu in 50 gb partition they both are in same hard disk and I have separate hard disk which is used simply for storage
    My fdisk -l output is

    Code:
    vaibhav@vrindavan:~$ sudo fdisk -l
    
    Disk /dev/sda: 80.0 GB, 80026361856 bytes
    255 heads, 63 sectors/track, 9729 cylinders
    Units = cylinders of 16065 * 512 = 8225280 bytes
    Disk identifier: 0x17e917e8
    
       Device Boot      Start         End      Blocks   Id  System

    I have first installed ubuntu and then windows
    now I am not able to figure out how to configure grub for windows boot my /boot/grub/menu.lst file is
    Code:
    # menu.lst - See: grub(8), info grub, update-grub(8)
    #            grub-install(8), grub-floppy(8),
    #            grub-md5-crypt, /usr/share/doc/grub
    #            and /usr/share/doc/grub-doc/.
    
    ## default num
    # Set the default entry to the entry number NUM. Numbering starts from 0, and
    # the entry number 0 is the default if the command is not used.
    #
    # You can specify 'saved' instead of a number. In this case, the default entry
    # is the entry saved with the command 'savedefault'.
    # WARNING: If you are using dmraid do not use 'savedefault' or your
    # array will desync and will not let you boot your system.
    default		0
    
    ## timeout sec
    # Set a timeout, in SEC seconds, before automatically booting the default entry
    # (normally the first entry defined).
    timeout		3
    
    ## hiddenmenu
    # Hides the menu by default (press ESC to see the menu)
    hiddenmenu
    
    # Pretty colours
    #color cyan/blue white/blue
    
    ## password ['--md5'] passwd
    # If used in the first section of a menu file, disable all interactive editing
    # control (menu entry editor and command-line)  and entries protected by the
    # command 'lock'
    # e.g. password topsecret
    ## password --md5 $1$gLhU0/$aW78kHK1QfV3P2b2znUoe/
    # password topsecret

    Re: ubuntu grub problem

    Hello vinu76jsr
    Try changing your Windows entry's 'root' line from (hd0,0) to (hd0,2), because Windows is in your third partition.

    Code:
    ### END DEBIAN AUTOMAGIC KERNELS LIST
    title        Windows XP
    root        (hd0,2)
    savedefault    
    makeactive    
    chainloader    +1
