if you had posted this before the new build was up i would have said to contact ms for a small fee they can send you and updated windows cd. right now your best bet is look on ebay for a updated windows 7 installer disk or ask if a friend has one. or go to a friends home with a 8g usb stick and make a new iso usb stick all you need is the windows iso to usb tool that free and windows iso that you can download from ms.
