Please read my post again. Linux Mandrake "comes with it",in most cases. In some cases you can buy one or both at a local Bookstore.
A LILO disk is created while you are installing the OS. You are instructed to do so by the install program for Linux.
Yes you can install on a blank disk.
First you need to go to a bookstore or better a Computer Store in your area and talk to someone there about the different Distributions for Linux.
Or you can search
www.amazon.com for it.
Buy either Mandrake or RedHat. They are two of the best versions.
Buy it, Load it, Report back...
