when i first started to use linux, i always saw this boot loader called GRUB.

then i wondered, what does GRUB stands for.. well, if you are reading this post most likely you want to know that too.

i am going to tell you then. GRUB stands for: Grand Unified Botloader

it is a flexible and advanced boot loader for the linux operating system. there are two other boot loaders used in linux: LILO and Linux Loader.

the location of GRUB is usually in the Master Boot Record (MBR) of the disk drive. you can also place it on the first hard disk sector of the / or /boot partition if you wish to use a boot loader from another operating system.
