Grub Customizer Ubuntu

Introduction to Grub Customizer

Grub Customizer is a type of graphical tool that permits users for customizing the Burg or bootloader GRUB 2 on Linux mint, 20.01, Ubuntu, and other operating systems. This graphical user interface tool helps to modify general things, like the boot order (menu entry sequence) to be created or the waiting time for the classical entry to automatically start. The Grub Customizer doesn't offer a full graphical user interface to configure every GRUB 2 subtleties.

The bootloader's role is to begin the operating system after a conventional BIOS or UEFI has started the hardware. The bootloader utilized today by most distributions is Grub 2 due to Grub 2 operating with UEFI and Bios and understanding every necessary file system, including the relatively fresh BTRFS. Also, the Grub 2 has one drawback: its complexity doesn't make adaptation simple.
