GRUB is abbreviation of GNU GRand Unified Bootloader. GRUB is a program by GNU that let the user choose the operating system if there are multiple operating systems installed on a single system. So if you have installed ubuntu or other distribution of linux then you must have seen the GRUB screen. On ubuntu, usually it is a purple colored screen. If you got bored from that simple, old purple background or you want to impress your friends, then read on. So in this post, I am telling you about changing the background image of GRUB.
#STEP 1
Its better to paste the image first in this folder using terminal:
sudo su
cd /usr/share
mkdir image
cp <---your image path like /home/navi/Desktop/ubuntu.jpg---> image/ubuntu.jpg
You can see the above screenshot. In this I have image in my /usr/share/image folder and the image is ubuntu.jpg . Firstly, my image ubuntu.jpg was in /home/navi/Desktop folder. Then I copied it to image folder in /usr/share.
#STEP 2 (Using Command-line)
In terminal type:
sudo su
Then goto the directory:
cd /etc/default
Then open the file “grub” using any editor. You may use vim, nano, gedit. So just change nano by any other:
nano grub
Then type the following command with absolute path of your image:
GRUB_BACKGROUND="/usr/share/image/ubuntu.jpg
#STEP 3
Then save the file.
In terminal type following command to update GRUB for the changes to take place:
update-grub
You will see the above output.
You can reboot now and skip next steps if you don’t want to change the text colors.
#To change the text color and highlight color of GRUB
In terminal type:
gksu gedit /etc/grub.d/05_debian_theme
Then locate:
if [ -z "${2}" ] && [ -z "${3}" ]; then
echo " true"
fi
Or just type Ctrl +f to find it write in it :
if [ -z or simply ‘z’.
Then replace the above paragraph with this one:
if [ -z or simply ‘z’.
Then replace the above paragraph with this one:
if [ -z "${2}" ] && [ -z "${3}" ]; then
echo " true"
echo " set color_highlight=red/green"
echo " set color_normal=light-cyan/black"
fi
Then save the file.
In terminal type following command to update GRUB for the changes to take place:

Then reboot the system.
Change the color accordingly or choose from the below list:
black, blue, brown, cyan, dark-gray, green, light-cyan, light-blue, light-green, light-gray, light-magenta, light-red, magenta, red, white, yellow
