Why can't debian modify the grub image?

Why can't debian modify the grub image? -- Debian information of the Linux release-the following is a detailed description. I use dual hard disks. The IDE0 primary disk is installed with XP, IDE1 is installed with Debian, IDE1 is divided into four areas,/boot,/, sweap, fat32, I have enabled grub.
Abc.xpm.gz copies/boot/grub and modifies menu. lst as follows: but the system prompts "Failed to read splash image (hd3, 0), grub, and abc when the server is started. Xpm. Gz) press any key to continue ...... Thank you.



# 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.

# Timeout sec
# Set a timeout, in SEC seconds, before automatically booting the default entry
# (Normally the first entry defined ).

### BEGIN AUTOMAGIC KERNELS LIST
# Lines between the automagic kernels list markers will be modified
# By the debian update-grub script failed t for the default options below

# 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
# Kopt = root =/dev/hdd2 ro

# Default grub root device
# E.g. groot = (hd0, 0)
# Groot = (hd1, 0)

# Shocould update-grub create alternative automagic boot options
# E.g. alternative = true
# Alternative = false
# Alternative = true

# Shocould update-grub lock alternative automagic boot options
# E.g. lockalternative = true
# Lockalternative = false
# Lockalternative = false

# Additional options to use with the default boot option, but not with
# Alternatives
# E.g. defoptions = vga = 791 resume =/dev/hda5
# Defoptions =

# Shocould update-grub lock old automagic boot options
# E.g. lockold = false
# Lockold = true
# Lockold = false

# Xen hypervisor options to use with the default Xen boot option
# Xenhopt =

# Xen Linux kernel options to use with the default Xen boot option
# Xenkopt = console = tty0

# Altoption boot targets option
# Multiple altoptions lines are allowed
# E.g. altoptions = (extra menu suffix) extra boot options
# Altoptions = (single-user) single
# Altoptions = (single-user mode) single

# Controls how many kernels shoshould be put into the menu. lst
# Only counts the first occurence of a kernel, not
# Alternative kernel options
# E.g. howtasks = all
# Howtasks = 7
# Howtasks = all

# Shocould update-grub create memtest86 boot option
# E.g. memtest86 = true
# Memtest86 = false
# Memtest86 = true

# Shocould update-grub adjust the value of the default booted system
# Can be true or false
# Updatedefaultentry = false
