Installing Grub Customizer on Ubuntu transforms the way you manage your bootloader by replacing complex command-line configurations with an intuitive graphical interface that anyone can use. This powerful tool lets you customize boot menus, change themes, adjust timeout settings, and manage multiple operating systems without touching configuration files.
What is Grub Customizer
Grub Customizer is a GUI-based application designed to simplify the management of GRUB2 (Grand Unified Bootloader), the default boot manager used in most Linux distributions including Ubuntu. Instead of manually editing system files like /etc/default/grub, this tool provides a user-friendly interface where you can make changes with just a few clicks.
Understanding GRUB Bootloader
GRUB controls which operating system or kernel version loads when your computer starts. Every time you power on your Ubuntu machine, GRUB presents a menu (if configured) allowing you to select between different operating systems or kernel versions. The bootloader plays a crucial role in dual-boot setups where Windows and Linux coexist on the same machine.
Why Use Grub Customizer
Manual GRUB configuration requires editing text files and running update commands, which can be intimidating for newcomers. Grub Customizer eliminates this complexity by offering visual controls for boot menu entries, timeout periods, default selections, and aesthetic customizations. It’s particularly valuable when managing multiple operating systems or frequently switching between different kernel versions.
Key Features of Grub Customizer
Grub Customizer packs numerous features that make bootloader management accessible to everyone, from beginners to advanced users.
Boot Menu Customization
You can reorder boot entries to prioritize your preferred operating system, rename menu items for clarity, and hide entries you rarely use. The drag-and-drop interface makes reorganizing boot options as simple as arranging files in a folder.
Visual Theme Management
The appearance settings tab allows you to install custom GRUB themes, change background images, modify font styles and colors, and adjust screen resolution. You can download themes from repositories like Pling and apply them directly through the interface.
Kernel Parameter Settings
Advanced users can add or modify kernel boot parameters without manually editing configuration files. This feature is essential for troubleshooting hardware compatibility issues or enabling specific system features at boot time.
Prerequisites Before Installation
Before installing Grub Customizer, ensure your system meets the basic requirements for a smooth installation process.
System Requirements
You need an Ubuntu system running version 22.04, 24.04, or newer. The tool works on Ubuntu-based distributions like Linux Mint, Pop!_OS, and elementary OS as well. Make sure you have an active internet connection to download packages from the PPA repository.
Required Permissions
Administrative privileges are necessary to install software and modify bootloader settings. You’ll need sudo access and your user password to execute installation commands. Grub Customizer requires root permissions to make changes to GRUB configuration since bootloader settings affect system-wide behavior.
Installing Grub Customizer on Ubuntu
The installation process involves adding a PPA repository and using Ubuntu’s package manager to install the software. Follow these steps carefully to ensure proper installation.
Step 1: Update System Packages
Open your terminal by pressing Ctrl+Alt+T on your keyboard. Run the following command to refresh your system’s package list and upgrade outdated software:
sudo apt update && sudo apt upgradeThis command ensures you’re working with the latest package information and security updates. Enter your password when prompted and press Enter to continue.
Step 2: Add the Official PPA Repository
Grub Customizer isn’t available in Ubuntu’s default repositories, so you need to add the official PPA maintained by developer Daniel Richter. Execute this command in your terminal:
sudo add-apt-repository ppa:danielrichter2007/grub-customizerThe PPA contains the latest stable release of Grub Customizer version 5.2.5. Press Enter when prompted to confirm adding the repository.
Step 3: Update Package List
After adding the PPA, refresh your package list again to include the newly added repository:
sudo apt updateThis step ensures Ubuntu recognizes the Grub Customizer packages available in the PPA.
Step 4: Install Grub Customizer Package
Now install Grub Customizer with the following command:
sudo apt install grub-customizerThe package manager will download Grub Customizer and its dependencies. The installation typically completes in less than a minute depending on your internet connection speed.
Step 5: Verify Installation
Confirm successful installation by checking the version:
grub-customizer --versionYou should see version information displayed in the terminal, confirming the tool is properly installed on your system.
Launching Grub Customizer
After installation, you can launch Grub Customizer through two different methods depending on your preference.
Opening from Application Menu
Click on the Activities menu in the top-left corner of your Ubuntu desktop. Type “Grub Customizer” in the search bar and click the icon when it appears. The application will prompt for your administrator password since it needs elevated privileges to modify bootloader settings.
Launching via Terminal
For quick access, open a terminal and run:
sudo grub-customizerThe graphical interface will launch after you enter your password. Using sudo is mandatory because GRUB configuration requires root permissions.
Using Grub Customizer Effectively
Once launched, Grub Customizer presents a clean interface with tabs for different configuration options.
Modifying Boot Order
The main tab displays all available boot entries in a list format. You can click and drag entries to reorder them, placing your preferred operating system at the top. Changes made here determine the order entries appear in the boot menu when your computer starts.
Setting Default Operating System
Select the entry you want to boot by default and move it to the top position. Alternatively, you can right-click an entry and select “Set as default”. The default system will automatically boot after the timeout period expires if no selection is made.
Adjusting Timeout Settings
Navigate to the General Settings tab to modify the timeout value. The timeout determines how many seconds GRUB waits before automatically booting the default entry. Set it to 0 for instant boot, or increase it to 10-30 seconds if you frequently switch between operating systems.
Customizing Boot Menu Appearance
The Appearance Settings tab offers extensive visual customization options. You can change the background image, select color schemes, modify font properties, and adjust screen resolution. Custom themes can dramatically transform the look of your boot menu from the standard text-based interface to modern graphical designs.
Advanced Customization Options
Grub Customizer provides advanced features for users who want deeper control over their bootloader.
Adding Custom Themes
To install a theme, download a .tar.gz theme file from sources like Pling. In Grub Customizer, click the Appearance Settings tab and select “Add theme”. Browse to your downloaded theme file and select it. The theme files will be extracted and applied to your GRUB configuration. Remember that some themes are distribution-specific and may not work on all systems.
Configuring Kernel Parameters
Advanced users can add custom kernel parameters by selecting a boot entry and clicking the edit button. Common parameters include quiet splash for minimal boot messages, or nomodeset for graphics troubleshooting. These parameters persist across kernel updates, unlike manual edits to configuration files.
Managing Multiple Operating Systems
When dual-booting or triple-booting, Grub Customizer automatically detects all installed operating systems. You can rename entries for clarity (like changing “Ubuntu” to “Ubuntu 24.04 Work System”), hide recovery mode entries to declutter the menu, or group similar entries together.
Troubleshooting Common Issues
Despite its user-friendly design, you might encounter occasional issues when using Grub Customizer.
Dependency Errors
Some Ubuntu versions, particularly newer releases like 25.04, may experience dependency conflicts. If you receive dependency errors during installation, try installing from the Debian repository as an alternative. Running sudo apt --fix-broken install often resolves missing dependency issues.
Boot Menu Not Updating
If changes don’t appear after rebooting, ensure you clicked the Save button in Grub Customizer before closing. The application must regenerate the grub.cfg file for changes to take effect. You can manually update GRUB by running sudo update-grub in the terminal.
Theme Installation Problems
Theme compatibility varies between GRUB versions and distributions. If a theme doesn’t display after installation, verify the theme file is in .tar.gz format and contains proper configuration files. Some themes require specific screen resolutions to render correctly. Try selecting “Custom resolution” in the Appearance tab and setting it to match your display.
Best Practices and Safety Tips
Following these guidelines helps prevent bootloader issues and ensures your system remains bootable.
Creating Backups
Before making significant changes, create a backup of your current GRUB configuration. Grub Customizer includes a backup feature accessible from the File menu. Store backups in a safe location so you can restore them if problems occur.
Testing Changes Safely
Make one change at a time and reboot to verify it works as expected. Avoid modifying settings you don’t understand, as incorrect boot parameters can prevent your system from starting. Keep a bootable Ubuntu USB drive handy for emergency recovery if bootloader issues arise.
Uninstalling Grub Customizer
If you need to remove Grub Customizer from your system, the process is straightforward. Open a terminal and run:
sudo apt remove grub-customizerTo completely remove the application including configuration files, use:
sudo apt purge grub-customizerFinally, remove the PPA repository with:
sudo add-apt-repository --remove ppa:danielrichter2007/grub-customizerYour GRUB configuration will remain intact after uninstalling Grub Customizer, preserving any changes you made.
