How to Install GRUB 2 and apply themes on Ubuntu Linux

New to Ubuntu Linux? This computer operating system could be a bit tricky for beginners, but fret not, help is here. Check out this video tutorial on how to install GRUB 2 and apply themes on Ubuntu Linux.

GNU GRUB is a multiboot boot loader. It was derived from GRUB, GRand Unified Bootloader, which was originally designed and implemented by Erich Stefan Boleyn.

Briefly, boot loader is the first software program that runs when a computer starts. It is responsible for loading and transferring control to the operating system kernel software (such as the Hurd or the Linux). The kernel, in turn, initializes the rest of the operating system (e.g. GNU).

GRUB 2 and GRUB Legacy

Currently under development, GRUB 2, has replaced what was formerly known as GRUB (i.e. version 0.9x), which has, in turn, become GRUB Legacy.

GRUB 2 aims at merging sources from PUPA in order to create the next generation of GNU GRUB. A mailing list and a wiki have been setup for discussing the development of GRUB 2.

Installation:

sudo apt-get install grub-pc

#install Grub 2 and will modify the existing grub boot loader menu.

Chainload into Grub 2? menu item press e to edit the configuration and change:

root xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

to

uuid xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

After the boot

sudo upgrade-from-grub-legacy

Now lets go for the theming

sudo apt-get install grub2-splashimages

cd /usr/share/images/grub/

ls

sudo gedit /etc/grub.d/05_debian_theme

replace the line

for i in {/boot/grub,/usr/share/images/desktop-ba se}/moreblue-orbit-grub.{png,tga}; do

with

for i in {/boot/grub,/usr/share/images/desktop-ba se,/usr/share/images/grub}/yourimage.{pn g,tga}; do
