Your cd/dvd program should have a function called disk copy. It will prompt you for a sorce disk (Your DVD with Win 7 on it), it will copy a image file to HDD. When done it will the prompt you to put in a Blank DVD and it will write the image on to the new DVD. Althoe windows 7 should have a program, I use IMGBURN. This is a free program that you can down load - Just goole imgburn.
