I recently installed the developer preview of windows 8 on my Retina MacBook Pro so I could play Battlefield 3. I saw that Windows 8 should take up less than 20GB of space, so therefore I created a 50GB partition size for the install via bootcamp. Once I finished the install, (I burned the image to a DVD and used an external drive) I was only left with 12GB of space left, only just enough for me to install Battlefield 3 from DVD, and not enough left (1.1GB) to get the updates for the game. I was also planning on installing SolidWorks on this partition. Has anyone else had an install of Windows 8 that took up 38GB??? I really need a functional use of windows but do not want to have to give up much of my limited space. Any ideas?
