I downloaded Windows 8 Enterprise, burned the iso image to a dvd, and try to install it using bootcamp. After setting the partition size (divide equally) I get the error message. What disc is it expecting? Well, now I get a new message saying bootcamp wants a 64 bit version. Since I have a dual core processor it would seem a 32 bit version would be appropriate, so that's what I downloaded. I guess I'll head back to the public library and download the other one. Takes about 17 minutes there.
