I am looking to put Windows on my Mac, but I would like to be able to boot natively into it in Boot Camp when I need to really work on a project or play a game, but would also like to be able to just fire up internet explorer for testing while just in OS X using VMware Fusion 4. I am on an Early 2011 MacBook Pro running Mac OS X Lion, 500 GB hard drive, and 16 GB of RAM. What is the best configuration for doing this? I am not looking to use Windows for much more than testing, but will be loading some 3D software and a game or two. The question I have are: 1) How much hard drive space should I give the Boot Camp partition? 2) Is there anything special I need to do to get Windows to activate right on both the Boot Camp partition, and in VMWare Fusion 4? 3) How much RAM should I assign in VMware is for the VM to run smoothly? Any other tips on this would be much appreciated.
