If you have your Grub upgraded to Grub stage 2 on ubuntu,you may enjoy adding a background picture to the Grub,so that your grub looks great when you boot up the computer!
First,make sure you have grub 2 upgraded.
Then,install grub2-splashimages by this command in terminal:
sudo aptitude install grub2-splashimages
Now,open up a file folder and navigate to filesystem->usr->share->images->grub.You’ll see many images,select one and copy the filename(without the extension .tga) to clipboard.
In terminal,run this command:
sudo gedit /etc/grub.d/05_debian_theme
Find the line “for i in {/boot/grub,/usr/share/images/…}…” and change it to for i in {/boot/grub,/usr/share/images/grub}/Fly-Angel.{png,tga} ; do. Here “Fly-Angel” is the filename of the picture.
Now,update and reboot to see the effect!
sudo update-grub
sudo reboot
