i think he will have to stick with a fat32 partition for the windows size because i think mac OSX cannot read the NTFS file system
Why does that matter? If the partitions are separate, it eliminates that problem. Besides, windows can't read HFS+ either.
Oh, and I thought the latest versions of OSX were NTFS compatible. I'm not sure, because I don't follow macs very closely, but I could have sworn I heard about that somewhere...
