Grub Customizer is a useful UI tool for modifying the default Grub boot loader settings. By using this tool, you can add, remove, and re-arrange boot menu entries. You can edit kernel parameters and also choose to change the time delay at boot, in order to boot from the default entry. The software also lets you make cosmetic configurations like changing the text color and background image.
In this article, we will explain how to install, launch and remove the software from your Ubuntu system. We have run the commands and procedures mentioned in this article on a Ubuntu 18.04 LTS system.
