Hi, I have a 16 GB USB stick that I wish to divide into 2 partitions: 1 FAT partition to use both on my mac and on windows computers. I want the other to be an bootable Mountain Lion partition. I have managed to make the bootable OSX partition (with Lion DiskMaker) and thereafter make a FAT partition. The problem is that this wont mount on windows computers. I read that the FAT partition needs to be first in order for windows computers to mount them. I have been trying around with the disk utility but it will not do as I ask it . Any suggestions on how I could manage this problem?
