Uhh,
Well, you boot off of the CD-ROM. If you can't- you make a floppy image from the "images" directory on the cd. Normally the cdrom.img or boot.img file. Use winimage or whatever to write it. dd if on *nix.
Boot to the floppy, with the cd in the drive and begin. It will format the drive for you, so what you did wasn't really necessary.
For a newbie install, whiteboxlinux is not what I would recommend. Whitebox is a cloned RedHat ES Server based OS. Which I'm guessing, you don't know much about. Servers, I mean. In any case, not to sound like a cliche'- but you been hoodwinked.
The easiest install would be Suse or Mandrake. Both are freely downloadable. You can tell which one's are most popular by looking at the
www.distrowatch.com site and scoping out the ratings.
So, that's how it goes. No matter what you install, if you can't boot off of a cd-rom, you will need to make a bootable floppy from the floppy.img or cdrom.img or boot.img or whatever. Good luck.
