So I just purchased a new 160GB HDD for my macbook in the hopes that I could run windows through boot camp. I threw the new hard drive in an enclosure and formatted it with Mac OS X extended (journaled) with one partition. Now, after swapping the drive out with my old internal drive and trying to run bootcamp, it gives me an error message saying that I need to reformat the drive with a single partition. Why!? I already did that. Do I really have to reinstall the OS and everything? I formatted the new disk via enclosure with Disk Utility and used Carbon Copy Cloner to transfer my old drive to the new drive. Any suggestions?
