You could always burn it to a USB stick and install from that. That is what I am doing. My NEW AlienWare Win7 build is 5.9Gbs. My next one will be even bigger as I add more features and newer modifications. My primary purpose here is to make an install disk that will work with my new MX-17 R3 laptop. It seems that the AW Win7 ultimate disk doesn't have the drivers to install on my laptop. I will be testing my build in a few minutes after I finish "burning" it to my 16G USB stick.
