Booting Linux
When you boot a PC, you cause it to
execute a small program known as a boot loader.
The purpose of the boot loader is to locate and read into memory the
first stage of an operating system and transfer control to it. The
operating system then locates and reads its remaining components as

The simplest way to boot Linux is by using a floppy diskette. By doing so, you’re able to leave the boot information on your hard drive untouched, ensuring that you can still boot Microsoft Windows or another operating system stored on the same hard drive. Moreover, some operating systems and virus protection programs prevent modification of the boot information on your hard drive. By booting from a floppy diskette, you avoid several potential problems.

floppy disk slow or inconvenient. You don’t have to boot Linux
from a floppy diskette; you can boot it in any of several other ways.
