Where does GRUB Legacy store its menu commands?

GRUB Legacy stores its menu commands in the /boot/grub directory. This directory contains configuration files that are essential for the bootloader's operation, including the grub.conf or menu.lst file, which defines the boot menu entries and their respective parameters.

This structure allows GRUB Legacy to access various boot configurations that can be modified by administrators. For instance, within the grub.conf or menu.lst, one can set the default operating system to boot, specify kernel parameters, and establish a timeout period for menu selection. The content is crucial for the boot process, as it directly influences how the system initializes upon startup.

Other options, while related to boot processes or GRUB, do not specifically store commands for GRUB Legacy. /etc/default/grub, for example, is primarily used by GRUB 2 to hold default settings, but it does not apply to GRUB Legacy. Similarly, /usr/share/grub and /boot/efi are relevant to GRUB and EFI environments but do not serve as the primary storage for GRUB Legacy's menu commands.
