Install and use Grub customizer on Ubuntu 20.04 or Linux Mint 20.02

The Grub Customizer is a graphical tool that allows users to customize the bootloader GRUB 2 or Burg on Linux Mint, 20.01, Ubuntu, and other similar operating systems. This GUI tool helps to change simple things such as the boot sequence (sequence of menu entries) to be made or the waiting time for the standard entry to start automatically. The Grub Customizer does not provide a complete graphical user interface for configuring all the subtleties of GRUB 2.

Well, the role of the bootloader is to start the operating system after UEFI or a conventional BIOS has initialized the hardware. The bootloader used today by almost all distributions is Grub 2 because Grub 2 works with Bios and UEFI and knows all the important file systems including the still relatively new BTRFS. Apart from the advantages, the Grub 2 has also one disadvantage that its complexity does not make adaptation easy.
