Try

sudo grub-mkconfig -o /boot/grub/grub.cf

and just for information, on which hard drive's MBR is grub2 installed on. (I can't understand grub.cfg)

Wrong path for your image (in /boot/grub/grub.conf)...

if background_image /boot/grub/Plasma-lamp.tga ; then

There should be no images in /boot/grub. They should be in /usr/share/images. See below.

And/or--
That error, (for me) usually indicates that there is a problem with this line...

for i in {/boot/grub,/usr/share/images/desktop-base}/Windbuchencom.{png,tga} ; do
in /etc/grub.d/05_debian_theme dealing with the grub background image...

# check for usable backgrounds
use_bg=true
if [ "$GRUB_TERMINAL_OUTPUT" = "gfxterm" ] ; then
for i in {/boot/grub,/usr/share/images/desktop-base}/Windbuchencom.{png,tga} ; do
if is_path_readable_by_grub $i ; then
bg=$i
case ${bg} in
*.png) reader=png ;;
*.tga) reader=tga ;;
*.jpg|*.jpeg) reader=jpeg ;;
esac
if test -e /boot/grub/${reader}.mod ; then
echo "Found Debian background: `basename ${bg}`" >&2
use_bg=true
break
fi
fi
done
fi
Make sure that the path/file name for the image looks similar to this (yours may be different)...

{/boot/grub,/usr/share/images/desktop-base}/Windbuchencom.{png,tga}
If that is correct make sure the image is in the folder specified. Mine are in...

/usr/share/images/desktop-base
so this line in my grub.cfg ends up like so..

if background_image /usr/share/images/desktop-base/Windbuchencom.tga ; then.


Your line in debian_theme should look like this (if your images are actually in /usr/share/images/grub)...

for i in {/boot/grub,/usr/share/images/grub}/Plasma-lamp.{png,tga} ; do

and your /boot/grub/grub.cfg will change to this after running update-grub again...

if background_image /usr/share/images/grub/Plasma-lamp.tga ; then

Mate, you are a legend.
I dont know how it happened but there was no image present on
/usr/share/images/desktop-base

I just put one image in there. and updated grub. it worked like a charm.
Thank you very much. this nifty problem were eating my head.

Glad to see you got it working.

Aside...
If you want to play around (and you have the hard drive space) without mucking up your working system install some kind of virtualization app (VirtualBox, VMWare, etc) and then load up Ubuntu (or whatever distro you want) on it. That way you can tweak it until it breaks without damaging your normal installation. Just remember that 3d support is iffy at best with most virtualization programs and they usually use their own drivers (not direct access to physical hardware). That situation is improving though.
