GRUB : Grand Unified Bootloader
GRUB stands for Grand Unified Bootloader. It is mostly used on linux operating system. The primary function of GRUB is to take over control from BIOS and load the kernel into memory. It supports multiple kernel images to be installed and and allows the users to choose the one to boot from. Once the kernel execution is done by the GRUB then the control goes to the kernel and GRUB is no longer needed unless the system reboots.
