GNU GRUB (or just GRUB) is a
boot loader package that supports multiple operating systems on a computer. During
boot-up, the user can select the operating system to run. GNU GRUB is based on an earlier multiboot package,
GRUB (GRand Unified Bootloader). GRUB is most often used on
Unix-like systems,
including GNU,
Linux and
Solaris.
