Install Grub Customizer on Fedora Linux via DNF

Step 1: Update Fedora Before Grub Customizer Installation

Let’s start by making sure your Fedora system is up-to-date. This step is crucial to ensure that all installed packages, including the DNF package manager, are at their latest versions, improving the system’s security and stability. Run the following command in your terminal:

sudo dnf upgrade --refresh

The upgrade command updates all the installed packages, while the --refresh flag forces DNF to synchronize its package database with the server before performing the upgrade operation. This ensures that DNF is aware of the latest versions of all packages.

Step 2: Install Grub Customizer via DNF Command

Now that your Fedora system is up-to-date, we’ll install Grub Customizer. For that, we’re going to utilize DNF’s install command, which fetches and installs the specified package along with its dependencies.

To install Grub Customizer, execute the following command:

sudo dnf install grub-customizer

This command will locate the Grub Customizer package in the Fedora repository, download it, and install it.

Initiating Grub Customizer on Fedora Linux

This section will discuss how to launch Grub Customizer on your Fedora system. You can use two primary methods to achieve this, either through the Command-Line Interface (CLI) or the Graphical User Interface (GUI). Both ways are simple, each with its advantages.

Method 1: Launch Grub Customizer via CLI

Launching Grub Customizer via CLI might be the preferred method for those who often work with the terminal and appreciate its efficiency. It’s pretty simple. All you need to do is open your terminal application (which could be GNOME Terminal, Konsole, xterm, or others, depending on your preferences and installed programs) and type the following command:

grub-customizer

After pressing the enter key, this command initializes the Grub Customizer tool, allowing you to start managing and customizing your GRUB boot entries directly from your terminal.

Method 2: Launch Grub Customizer via GUI

Launching Grub Customizer via the GUI is ideal for users who are more comfortable navigating through visual menus and icons. It is a straightforward process, as follows:

1. Start by clicking on ‘Activities’ at the top left corner of your screen.
2. Click on ‘Show Applications’ – usually represented by a grid of dots at the bottom of the dock.
3. In the applications menu, search for ‘Grub Customizer’ by typing it into the search bar at the top.
4. Click on the ‘Grub Customizer’ icon to launch the application.

• Renaming Entries: You can easily rename any boot entry by double-clicking on it and editing the title.

Cautionary Grub Customizer Tips on Fedora

While Grub Customizer offers robust functionality, remember that it’s a tool for editing one of the most critical parts of your Linux system, the bootloader. Here are some cautionary tips:

• Backup before Changes: Always remember to back up your current GRUB configuration before making any changes. You can restore your GRUB to its previous state if something goes wrong.
• Careful with Removing Entries: Be cautious when removing boot entries. If you remove the wrong one, it could prevent your system from booting.
• Avoid Unnecessary Changes: Avoid making changes to entries or settings you don’t understand. Breaking things in GRUB is easy; some changes can lead to an unbootable system.
