Windows 7 USB install problems

My hard drive that came with my m17x died, so I picked up a new hard drive to replace it so that I can get it to work again. I lost my recovery disc that came with the alienware, so I had to do a USB install. When I press install now for windows 7 home premium a message appears saying "No device drivers were found. Make sure that the installation media contains the correct drivers, and then click OK." What do I have to do to fix this so I can get Windows back on my M17x R4?
