BUT.... what problems have people run into migrating from boot camp to Fusion.. especially concerned over partition issues? gwd ...
i have a good proposal that might work nicely for you.
1. install bootcamp (using Bootcamp Assistant that comes with your Mac), then install Win7 (it will walk you through how to)
2. insert the grey Snow Leopard OS disc you have to install the Win7 drivers for the computer, etc.
3. DO NOT register win7 - you will have the usual 30 days to play around.
if, within that time, you are comfortable, register it by all means! if you want to give VMware a go (i recommend Parallels), install/buy you VM software and link the VM to your Bootcamp install. so long as you havent registered it wont worry about the hardware.
having setup both Bootcamp + your VM to boot from the same Win7 partition, you can easily choose either method to boot, open VM, or restart for better GPU support and whatnot.
hope this helps
