"I guess all the DVD's I made of Windows from TechNet downloads are not bootable. ???? ". That says you don't know if some DVD's you made are bootable or not--I suggested you try one to see if it indeed boots, then you'll know. Set the Bios to boot from the DVD first, put a DVD in the drive, power down then power up and see if it boots to the DVD. That seems so straight forward and simple I must not understand your problem.
