It boots just fine. I select the Language, Time settings, Keyboard or input method and hit the next button. Then I click on the "Install Now" button and thats when I get the error message reading, "A required CD/DVD drive device driver is missing. If you have a driver floppy disk, CD, DVD, or USB flash drive, please insert it now."
From the link you provided earlier, it sounds like that is when I am supposed to input the Product Key, but I never get to that point.
