Before you start
This tutorial shows you how to install and use GRUB, the Grand Unified Boot Loader. GRUB can help you improve the reliability and availability of your Linux system.
If you want just a taste of GRUB, read the first three sections of this tutorial and make a GRUB boot floppy, and then practice using it to boot your system. By doing so, you'll learn how to use GRUB to boot your system in case of an emergency.
If, however, you want more in-depth experience with GRUB, continue reading GRUB internals, which shows you how to set up GRUB as your default boot loader.
You should be somewhat familiar with LILO and have a basic working knowledge of disk partitions.
