5 easy steps change grub2 background image splash screen

In this tutorial I will share the steps to change background image of your GRUB2 menu which is also referred as splash screen in Linux. The default splash screen varies across different Linux distributions. In this article I will use RHEL 8 but the same steps would be valid for any other distribution using GRUB2 such as Ubuntu, Debian, CentOS, SuSE etc.


1. Default GRUB2 background image

With my Linux distribution, below is the default GRUB2 background image.

As you see, it is a plain black background image. In default RHEL distribution they use isolinux/splash.png which is nothing but a plain background image.


2. Place your custom image on the server

You can use JPG/JPEG or PNG images as your new background image instead of the default splash screen. make sure the image resolution is 600*600 or higher. You can put the image any preferred location, we will create a new directory /boot/grub2/images

# mkdir /boot/grub2/images

Next copy your image inside this directory

# ls -l
total 384
-rw-r--r-- 1 root root 363046 Aug 28 13:39 RHEL_8_Desktop.png

So now we have our image. Let's go to the next step.


2. Update GRUB2 with new background image

Update your GRUB2 and add or modify below variables in /etc/default/grub

# cat /etc/default/grub
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
#GRUB_TERMINAL_OUTPUT="console"  <-- Commented out this entry
GRUB_CMDLINE_LINUX="resume=/dev/mapper/rhel-swap rd.lvm.lv=rhel/root rd.lvm.lv=rhel/swap rhgb quiet biosdevname=0 net.ifnames=0"
GRUB_TERMINAL_OUTPUT="gfxterm"   <-- Use gfxterm
GRUB_BACKGROUND="/boot/grub2/images/RHEL_8_Desktop.png"  <-- provide the location of your image


4. Rebuild GRUB2

Next rebuild your GRUB2 configuration on legacy BIOS

# grub2-mkconfig -o /boot/grub2/grub.cfg
Generating grub configuration file ...
Found background: /boot/grub2/images/RHEL_8_Desktop.png


5. Verify the new GRUB2 background image

We are all set, next reboot the node and verify your new GRUB2 background image

So now we have our new GRUB2 background image



In this turorial we learned about how we can change the GRUB2 background image with our own splash screen. These steps are tested only on running Linux environment and not on custom ISO DVD. The steps required to change GRUB2 background image in ISO dvd will vary. Since I do not have a UEFI environment, I could not verify that part. if you face any issues kindly drop in a comment available at the bottom of this article.

  1. If you’re using a Debian-based distribution, you can do all things grub including setting the background image using the grub-customizer package.It’s in the standard repos now. Prior to 20.04 it was available in a PPA.
