Installed Windows using Boot Camp and created the USB key via the automated steps. Unfortunately, the installation created a W7 Home install vs the W7 Professional (that I own) and now cannot activate since the key isn't recognized for Home. Thinking it is just a flaw in the automation, as I can't find any steps during the installation to verify/correct the type of install. UPDATE, so I tried again simply using the ISO to USB software from Microsoft thinking it was a problem in the Apple conversion but same outcome - it installs the Home edition. I got it to correctly install Professional when I opted for the DVD-based install.
