I'm trying to clone the drive from a Dimension 2400 to a Dimension 4700 with a 80G USB Drive. I cloned the image from the 2400 onto the USB with no problems, but trying to load the image to the 4700 is causing a Windows Blue Screen. I checked the bios to allow USB boot devices, but no luck. I've done this serveral times with 4700 machines with no issues. Am I missing something.
