GNU GRUB (short for GNU GRand Unified Bootloader) is a boot loader package from the GNU Project. GRUB is the reference implementation of the Multiboot Specification, which provides a user the choice to boot one of multiple operating systems installed on a computer or select a specific kernel configuration available on a particular operating system's partitions.
GNU GRUB was developed from a package called the Grand Unified Bootloader (a play on Grand Unified Theory). It is predominantly used for Unix-like systems. The GNU operating system uses GNU GRUB as its boot loader, as do most Linux distributions. The Solaris operating system has used GRUB as its boot loader on x86 systems, starting with the Solaris 10 1/06 release.

Famous quotes containing the word grub:
“I have tasted but little bread in my life. It has been mere grub and provender for the most part. Of bread that nourished the brain and the heart, scarcely any. There is absolutely none on the tables even of the rich.”
—Henry David Thoreau (1817–1862)
