Hi Reschke,
Can you give us a bit more info to clarify things... What do you mean by "boot screen". Do you mean entering BIOS? In BIOS, have you confirmed that the DVD drive is listed in the devices shown? Have you confirmed that the system is set to boot to the DVD drive BEFORE it tries to boot from the hard drive?
You mention that it's a "new system". Does it have a floppy disk drive? If so, disconnect it for now.
