Hi when you first turn your computer on It should flash up on the screen press "Del" or "F10" to enter BIOS (This can vary from computer to computer just closely watch the screen when your computer first turns on.)
Once In the BIOS have a look through the options available one by one. You will find an option saying Boot Order. By the sound of it your computer is trying to boot from a floppy first all you need to do is change the boot order so that it boots first from your hard drive or your DVD-ROM/CD-RW. Basically just change the order your computer boots in and set the floppy till last that should help speed up your boot up.
I think the problem is windows based rather than being controlled by the bios, have a look at the link for a similar problem
Bluemonkey do you have a small home network?
