Linux Boot Loader
Linux boot loaders in use today include LILO and GRUB. If no boot loader is used, then loadlin acts as the boot sector loader.
LILO: LInux LOader
- UNIX text-based boot loaders adapted for Linux
- very structured config file /etc/lilo.conf
- limited security features
GRUB: GRand Unified Boot-loader shell
- modern replacement for LILO
- more like a special-purpose shell than an boot loader application
- text or GUI based interface and config
- structured config files in /boot/grub
- very good security features
