Main Configuration File for GNU GRUB

menu.lst -or- grub.conf -or- grub.cfg

GNU GRUB (GRand Unified Bootloader) is a widely used boot loader for Linux and other Unix-like operating systems. The main configuration file for GNU GRUB is typically located at /boot/grub/grub.cfg. However, the question asks for the name of the file without any path.

The name of the main configuration file for GNU GRUB is simply "grub.cfg". This file contains the configuration settings and options for the boot loader, including the list of available operating systems and the default boot option.

It is worth noting that while the grub.cfg file is the main configuration file for GNU GRUB, it is generally not recommended to edit this file directly. Instead, configuration changes should be made to the files located in the /etc/grub.d directory, which are used to generate the grub.cfg file. After making changes to these files, the grub.cfg file can be regenerated using the grub-mkconfig command.
