I am trying to install Windows 7 via bootcamp. I am an MSDN subscriber so I just grabbed the Win7 ultimate 64bit with sp1 from the msdn site. I am getting an error reporting that a required cd/dvd driver was not found. After researching this on the net, people are reporting it is because of a corrupt iso. I have checked the SHA1 checksums and they match. I have tried creating the USB stick 3 times now, no difference. What else could be wrong?
