How to Install GRUB Themes

Install a New Theme

1. Find and download a theme Browse
2. Run the following commands in a terminal window:
   # change to ~/Downloads directory
   cd ~/Downloads
   # list the contents of the directory
   ls
   # extract the downloaded theme, replace the file name as needed
   tar xzvf 'Grub2-theme CyberRe 1.0.0.tar.gz'
   # copy the extracted theme to /boot/grub/themes
   # change the theme name as needed
   sudo cp CyberRe\ 1.0.0/CyberRe /boot/grub/themes/ -r
   # backup /etc/default/grub
   sudo cp /etc/default/grub /etc/default/grub.bkup
   # edit /etc/default/grub
   sudo nano /etc/default/grub
3. At the bottom of the file, paste the following, updating the path to the theme.txt file

   GRUB_THEME=/boot/grub/themes/CyberRe/theme.txt

4. Press CTRL+O, Enter, CTRL+X to write the changes
5. Continue with the following commands in a terminal window:
   # update grub
   sudo update-grub
6. If everything is setup correctly, a line that reads Found theme: /boot/grub/themes/CyberRe/theme.txt should show in the update-grub output
7. Reboot to see the new theme in action

Removing the Theme

1. Run the following commands in a terminal window:
   # change to the grub themes directory
   cd /boot/grub/themes/
   # list the contents of the directory
   ls
   # recursively remove the custom theme directory
   # replace the theme folder name as needed
   sudo rm CyberRe -r
2. NOTE: You can also remove the GRUB_THEME= line from /etc/default/grub, but it is not required

   # update grub
   sudo update-grub
   # reboot
   sudo reboot now
