I bought a new Dell computer recently and I was interested in cleaning the hard drive. I have a nice program that I burned to disk called Darik's Boot and Nuke. However when I reboot the computer and press f12 to go into the boot menu the program will not work. How can I make  the program work from a cd? The last time I used the program on my old computer I used a floppy drive and  I didn't have any problems.

My computer is a Dell Studio D540. Intel Core 2 processor Q8200.
