Making a Linux Boot Disk

Introduction
    A Linux boot disk contains the kernel image and any other programs that are necessary to get the machine to boot. A boot disk can be used to rescue a machine that will no longer boot properly. This type of boot disk can be used to boot the system if LILO is corrupted but the root filesystem is intact. Since this boot disk attempts to mount the root filesystem, a kernel panic will result if the root filesystem has also been corrupted and cannot be mounted. In this situation, it is necessary to have a root disk to repair the filesystem.

Using the mkbootdisk command
    Insert a blank, formatted floppy disk and execute the following command at the command line:
mkbootdisk 2.2.12       (where 2.2.12 is the version number of the Linux kernel that you wish to use).
