longDescription =
|

'' GNU GRUB is a Multiboot boot loader. It was derived from GRUB, GRand
|
|
Unified Bootloader, which was originally designed and implemented by
|
|
Erich Stefan Boleyn.
|
|
|
|
Briefly, the boot loader is the first software program that runs when a
|
|
computer starts. It is responsible for loading and transferring
|
|
control to the operating system kernel software (such as the Hurd or
|
|
the Linux). The kernel, in turn, initializes the rest of the
|
|
operating system (e.g., GNU).
