Howto Change Grub2's (Grub-PC) Splash Image On Ubuntu

You can read my previous blog post about upgrading/installing GRUB2 on Ubuntu Jaunty and Karmic Koala here.We installed Grub2 but found its default splash ugly and we want to change it.Let's start the howto by installing grub2-splashimages package :

$sudo apt-get install grub2-splashimages

Now we have a couple grub2 themes under /usr/share/images/grub/ folder.Let's select a grub2 theme from the following folders :

/usr/share/images/desktop-base/
/usr/share/images/grub/

$ls /usr/share/images/grub/

My output :

BLABLABLABLA
Moraine_Lake_17092005.tga TulipStair_QueensHouse_Greenwich.tga
BLABLABLABLA

In this howto i am selecting Moraine Lake splash image.Note down the name of the file and edit the following file :

$sudo gedit /etc/grub.d/05_debian_theme

Search for this line :

for i in {/boot/grub,/usr/share/images/desktop-base}/moreblue-orbit-grub.{png,tga}

And change it to :

for i in {/boot/grub,/usr/share/images/desktop-base,/usr/share/images/grub}/Moraine_Lake_17092005.{png,tga}

This basically tells GRUB2 to look for image name “Moraine_Lake_17092005” in the following locations:

/boot/grub
/usr/share/images/desktop-base
/usr/share/images/grub

Do not forget to change "Moraine_Lake_17092005" with your selected theme's name.Save and exit.

Now we have to regenerate grub's config (grub.cfg) with the following command :

$sudo update-grub

Reboot and test your Grub2 theme.

PS: The output of $update-grub command should look like this (BOLD one) :
Generating grub.cfg ...
