I'm having a problem with installing Windows 7. I can boot off of the DVD with out a problem. I get to the screen for language selection and such. I click next and get the screen that says click to install. I click install now and shortly after I get a box that says a required CD/DVD drive device driver is missing. This happens with both 32 and 64 bit versions. I have tried extracting the contents of the Boot Camp folder on my Snow Leopard DVD to a USB drive. Windows setup will see all the drivers, but there doesn't seem to be one for the CD/DVD drive. Any suggestions would be helpful. I am running a MacBook 4,1.
