Chapter 4. Boot Methods
This chapter describes some techniques for booting your Linux system.

Choosing between operating systems is generally referred to as dual booting, but you can boot more than two (e.g., Linux and Windows 95/98/NT/2000). This chapter covers the following topics:
The boot process
LILO: the Linux loader
Loadlin: booting from MS-DOS
Dual booting Linux and Windows NT/2000
Boot-time kernel options
initrd: using a RAM disk
