To start off you guys are always so helpful and I really appreciate it. Ok I received my Windows XP Pro 32 bit disc today and plan to install tonight. I plan on using Fusion and I plan on running autocad and two 3d cabinet design programs. Should I use Boot Camp to create my partition and then download Fusion later or should I use Fusion to install Windows? Also if I use Boot Camp and then install Fusion I will have the option to boot into Windows natively at start up if I would like, correct? Also I plan on running AutoCad 2000 LT. I have read there are problems with a deactivating serial number. Does anyone have issues with this? Reccomendations on amount of hard drive space I should allocate for Windows? Thanks again everybody!
