How To Set a Theme for Ubuntu GRUB

Ubuntu 15

In this guide, we will walk you through the process of setting a theme for the GRUB bootloader in Ubuntu. GRUB, which stands for Grand Unified Bootloader, is the default bootloader for most Linux distributions, including Ubuntu. By default, GRUB is not the most aesthetically pleasing part of your system, but don’t worry, you can customize it with themes to make it look better.

Quick Answer

To set a theme for the GRUB bootloader in Ubuntu, you can either manually install a theme by downloading and extracting it to the /boot/grub/themes/ directory, or use a deb package or auto-installer provided by the theme. Alternatively, you can use the grub-customizer tool for an easier way to manage GRUB themes.

What is GRUB?

GRUB is a bootloader, which is the first software program that runs when a computer starts. It is responsible for loading the kernel of an operating system and then transferring control to it. The kernel, in turn, initializes the rest of the operating system.

Finding a GRUB Theme

Before we start, you’ll need to find a GRUB theme that you like. There are many websites where you can find GRUB themes, but one of the most popular is gnome-look.org.

Installing a GRUB Theme

There are two main methods to install a GRUB theme:

Option 1: Manual Installation

  1. Download and Extract the Theme Download your preferred theme and extract it to the /boot/grub/themes/ directory. If the theme comes in a compressed format like 7z, you can use the command 7z x [theme_file.7z] to extract the theme files. Replace [theme_file.7z] with the actual filename.
  2. Edit the GRUB Configuration File Open the /etc/default/grub file using a text editor with root privileges. You can use sudo nano /etc/default/grub to open this file in the nano text editor. Locate the line starting with “#GRUB_THEME” and uncomment it by removing the ‘#’ at the start. Change it to “GRUB_THEME=/boot/grub/themes/[THEME_FOLDER]/[theme.txt]”. Replace [THEME_FOLDER] with the name of the theme folder and ensure that [theme.txt] is the correct text file for the theme.
  3. Update GRUB Save the changes to the /etc/default/grub file and exit the text editor. Then, run the command sudo update-grub to update the GRUB configuration. This command generates a new configuration file incorporating your changes.

Option 2: Using a Deb Package or Auto-installer

Some themes may provide a deb package or an auto-installer.

  1. Download and Run the Installer Download the deb package or run the auto-installer script provided by the theme. This will automatically install the theme files in the correct location.
  2. Edit the GRUB Configuration File As with the manual installation, open the /etc/default/grub file in a text editor with root privileges, locate the “#GRUB_THEME” line, uncomment it, and change it to point to the correct theme file.
  3. Update GRUB Save the changes and exit the text editor. Run sudo update-grub to generate a new GRUB configuration file.

Using Grub Customizer

For an even easier way to manage GRUB themes, you can use the grub-customizer tool. This tool provides a graphical interface for managing GRUB settings and themes. To install grub-customizer, run the following commands in a terminal:

sudo add-apt-repository ppa:danielrichter2007/grub-customizer
sudo apt update
sudo apt install grub-customizer

With grub-customizer, you can easily select and apply different themes without manually editing the configuration file.

Conclusion

Customizing the GRUB bootloader with a theme can make booting your system a more pleasant experience. Whether you choose to manually install a theme, use a deb package or auto-installer, or use the grub-customizer tool, you now have the knowledge to make GRUB look the way you want. Remember, if you encounter any issues, refer to the documentation or support provided by the theme or grub-customizer tool. Happy customizing!
