The diskettes are used to let you use your CD when it is NOT CD bootable. In other words, change your bios back to boot from floppy then reboot. The diskettes contain drivers to recognize your CD so that you can install to a clean disk without an OS present.

If your PC allows you to boot from CD, you are not doing it properly. Set your bios sequence to boot in the following order:

1. CD
2. HDD
3. Floppy.

Now when you press reset, or turn your system on, it will get to a screen that will tell you to press any key to boot from CD. If you are late and miss this prompt, it will attemp to boot from HDD and give you an "invalid disk" halt.
