Did you also load video driver(s)? You may simply load all of them using

insmod all_video

correct driver should be autodetected (or so the theory :) ).

Hello Andrei,

The command works!! Thanks so much for your help.

But the image displayed in not good. It seems all the 24 bits are not being used.

Can grub2 display 24 bit images?
