I just chose 32GB for a Bootcamp partition then installed Windows 7 + SP1 (i.e. the install media already has SP1 included rather than downloading later. After install I only had about 2GB space left - has anyone else noticed this? I was using Ultimate edition, I wonder if I should go for Pro or Home Premium instead. It is just for me to try a few games out. I am trying to keep the partition size down as I don't want to waste SSD space on it. A second question is can I install the BC partition on the hard drive in my iMac instead, I read a few things saying it could only be on the boot drive of the Mac?
