Berikut adalah cara untuk mengganti Gambar pada grub yang penulis gunakan pada waktu membuat distro Mbojonux
1) Create an image which you will want as your GRUB splash. It must have a resolution of 640×480, and it must have 14 colours. In GIMP, you can edit the number of colours by clicking on Image->Mode->Indexed. Save the image in XPM format (.xpm).
2) Gzip the image by typing into the console:
gzip image.xpm
Where “image.xpm” is the image file you created (with its location, if you’re not already in that directory). If you do not have permissions, remember sudo too.
3) Create a GRUB image directory and move the new image file into it.
sudo mkdir /boot/grub/images
sudo mv usplash.xpm.gz /boot/grub/images
4) Change the GRUB menu file to load the image.
sudo cp /boot/grub/menu.lst /boot/grub/menu.lst.old
sudo kwrite /boot/grub/menu.lst
Find the following (row 24 or therabout):
# Pretty colours
#color cyan/blue white/blue
Add there:
splashimage=(hdX,Y)/boot/grub/images/image.xpm.gz
NOTE: Replace X and Y with the proper numbers! X in this case is the actual disk drive and Y is the partition. Assuming you have a pretty standard installation of Kubuntu, you could find this information further down in menu.lst. Locate the section which matches the entry you normally boot from:
## ## End Default Options
## title Kubuntu, kernel 2.?.??-?-??
root (hdX,Y)
There you can find the proper numbers to use for your splashimage command. Enter those in the line added before. If you have a separate boot partition you have to remove the /boot in the path, this is because the root of the boot partition is mounted in /boot on your other partition. Resulting in this section instead:
splashimage (hdX,Y)/grub/images/usplash.xpm.gz
5) Update GRUB.
sudo update-grub
Restart and voila!
