    Ubuntu / Windoze XP Dual Boot On RAID Drives, Now Grub Problems!


    I just got a new laptop, and it has a RAID setup. So, I need to do a dual boot setup to run XP since I need to use it for work. I found this article, and have followed all the way through. Now I've got a problem booting into Ubuntu, but Windoze will boot fine.

    https://help.ubuntu.com/community/FakeRaidHowto

    I get a "Error 15: File not found" when I choose Ubuntu to boot.

    I figure I've messed up my grub config somewhere, so I'm trying to mount the drives after booting from the live CD to alter the config.

    Here is my grub config:
    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 change this entry to 'saved' 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
    password --md5 $1BHNKOi1$nKcoqvcZUGHh6TJCLlEu4.

    ### BEGIN AUTOMAGIC KERNELS LIST
    ## lines between the AUTOMAGIC KERNELS LIST markers will be modified

    ## DO NOT UNCOMMENT THEM, Just edit them to your needs
    
    ## ## Start Default Options ##
    ## default kernel options
    ## default kernel options for automagic boot options
    ## If you want special options for specific kernels use kopt_x_y_z
    ## where x.y.z is kernel version. Minor versions can be omitted.
    ## e.g. kopt=root=/dev/hda1 ro
    ##      kopt_2_6_8=root=/dev/hdc1 ro
    ##      kopt_2_6_8_2_686=root=/dev/hdc2 ro

    ## default grub root device
    ## e.g. groot=(hd0,0)
    # groot=(hd0,4)
    
    ## should update-grub create alternative automagic boot options
    ## e.g. alternative=true
    ##      alternative=false
    # alternative=true
    
    ## should update-grub lock alternative automagic boot options
    ## e.g. lockalternative=true
    ##      lockalternative=false
    # lockalternative=true
    
    ## additional options to use with the default boot option, but not with the
    ## alternatives
    ## e.g. defoptions=vga=791 resume=/dev/hda5
    # defoptions=quiet splash
    
    ## altoption boot targets option
    ## multiple altoptions lines are allowed
    ## e.g. altoptions=(extra menu suffix) extra boot options
    ##      altoptions=(recovery mode) single
    # altoptions=(recovery mode) single
    
    ## controls how many kernels should be put into the menu.lst
    ## only counts the first occurence of a kernel, not the
    ## alternative kernel options
    ## e.g. howmany=all
    ##      howmany=7
    # howmany=all
    
    ## should update-grub create memtest86 boot option
    ## e.g. memtest86=true
    ##      memtest86=false
    # memtest86=true
    
    ## should update-grub adjust the value of the default booted system
    ## can be true or false
    # updatedefaultentry=false

    So can anyone tell me what bone headed thing I've done wrong? I'm really stuck here.
