Running Fusion gives two options to install Windows...a Windows Easy Install or using an existing Boot Camp Partition. Seems there are advantages to installing off of the BC Partition. Should I go ahead and install Boot Camp first?
If you plan to *use* Boot Camp then you should install it first. Don't just do it for the sake of doing it, as it will gobble up a fixed portion of your hard drive and it's not easy (might not even be possible) to adjust the amount of space used without reinstalling from scratch.
