Bootloading with *GRUB2*
*GRUB2* is the latest version of *GNU GRUB*, the _GRand Unified Bootloader_.
A bootloader is the first software program that runs when a computer
starts. It is responsible for loading and transferring control to the
operating system kernel. In Fedora, the kernel is Linux. The kernel then initializes
the rest of the operating system.
*GRUB2* is the follower of the previous version *GRUB* (version 0.9x). The original version is available under the name *GRUB Legacy*.
Since Fedora 16, *GRUB2* has been the default bootloader on x86 BIOS systems. For upgrades of BIOS systems, the default is also to install *GRUB2*, but you can opt to skip bootloader configuration entirely.
