Hello, I have a 15" MBP, Mid 2012 with 8gb of RAM and 750gb HD running 10.8.3. I'm trying to dual boot Windows 7, but I'm also trying to make a third partition formatted in FAT32 so that I can have access to certain files while I'm booted in either OS. So I partitioned my HD with with 100gb for the WINDOWS partition, 100gb for the SHARED partition, and I resized Macintosh HD to whatever was leftover. Then when I went to go install Windows, I could only pick the WINDOWS partition--it had called my FAT32 partition "unallocated disk space" and it was not considered a "primary" drive. Despite both drives being formatted with the same file system, Windows only recognized the first one as a viable installation location. So I formatted that partition, NTFS, and installed Windows. It worked fine, however I cannot see that last 100gb of SHARED in Windows. In Windows' version of Disk Utility, I was able to look at that free space but if I were to partition it, I see this warning message saying that I will not be able to boot to any other operating system on the drive if I format those 100gb into a "Dynamic Partition". Needless to say I don't want to lose Mac, and I also want to get this to work. If anyone has any information they could share about resolving this it'd be greatly appreciated. Also if you need more info from me, screenshots and whatnot, I'd be happy to oblige. And no, I don't want to download an NTFS driver for Mac or just use a virtual machine. Thanks.
