The Grub Customizer is a graphical tool that allows users to customize the GRUB 2 or Burg boot loader on Linux Mint, 20.01, Ubuntu, and other similar operating systems. This GUI tool allows you to change simple things such as the boot sequence (sequence of menu entries) to perform or the time to wait for standard input to start automatically. The Grub Customizer does not provide a full graphical user interface to configure all the intricacies of GRUB 2.
Well, the role of the bootloader is to boot the operating system after UEFI or a conventional BIOS initializes the hardware. The bootloader used by almost all distributions today is Grub 2 because Grub 2 works with Bios and UEFI and knows all important file systems including the still relatively new BTRFS. Apart from the advantages, the Grub 2 also has a disadvantage that its complexity does not make adaptation easy.
Here we will learn how to install this Grub graphical customizer on Ubuntu 20.04 LTS or Linux Mint 20.2.
Install Grub Customizer on Ubuntu 20.04 or Linux Mint
1. Run the system update
Before installing anything, let’s run the update system command to update the packages installed on it. Also, it will update the system.
sudo apt update
2. Install Grub Customizer on Linux mint or Ubuntu 20.04
The packages to install Grub Customizer are already there in the base repository (archive.ubuntu.com) to install on the system, just run the command below:
sudo apt install grub-customizer
To check the version of the installed tool, you can use the command:
3. Run Grub Customizer
The installation is complete now, let’s run the same. Go to all apps launcher and find this installed app. Alternatively, you can also use the command-
As we launch the tool, the system will ask you for the root password as it needs it to customize the Grub. In addition, the changes saved by the Grub customizer create a new “grub.cfg” file with the current settings with the defined settings.
Under the List for configuration, you will see all available bootloader entries. You will get all the entries so that they can be edited, renamed and deleted. Right click on the entry and select the “Edit“to open an editor for the script behind a boot entry, for example, to enter new boot parameters for a Linux system in the” Linux “line.
Under the General Settings page, the user will find important settings. Such as the standard boot entry to select and change the default, Show boot menu option, search for other operating system entries, and a field for boot wait time in seconds.
The last page of settings “Appearance”Controls the appearance of Grub and offers color settings, screen resolution, and selection of a background image.
If you want to use the custom background as your startup image, click the icon to the right of the Background Image drop-down list. And select the image which should be in PNG format, exactly match the defined resolution, and not have a space in the file name. Changes to menu colors only have an effect if a background image is selected, otherwise Grub 2 ignores the color information.
Well, there is a lot you can do with Grub Customizer, but you can’t remove old kernels that are no longer needed for system maintenance. For this you need to use a package manager.
If after a while you no longer need it, run the following command:
sudo apt remove grub-customizer
