A boot loader is a small program that reads
and launches the operating system. Fedora Core uses the
boot loader by default. If you have
multiple operating systems, the boot loader determines which one to
boot, usually by offering a menu.
You may have a boot loader installed on your system already. An
operating system may install its own preferred boot loader, or you
may have installed a third-party boot loader.If your boot loader
does not recognize Linux partitions, you may not be able to boot
Fedora Core. Use
as your boot loader to
boot Linux and most other operating systems. Follow the directions
in this chapter to install
If you install GRUB, it may overwrite your existing boot loader.
The following screen displays boot loader configuration options.
