Setup GRUB boot loader in 3 steps
GNU GRUB is easy to set up, it’s just got it’s own funky syntax that you don’t really see anywhere else.
===GRUB stands for GRand Unified Bootloader===
GNU GRUB is a multiboot boot loader derived from the original GRUB. It is the first software program that runs when a computer starts. It loads the kernel and … that’s it. It’s the kernel’s job to load the rest of the OS. GRUB was originally created by Erich Stefan Boleyn.
===Quick, easy, & painless===
Install grub. In gentoo i’ll just emerge it from the portage tree. You may have to download the source manually or perhaps use your package manager to install from a binary.
