There's an alternative if you have already formatted your disk and didn't follow that order:

One needs to understand that one can very well format a disk in GPT instead of MBR scheme and _later_ add a MBR. While Windows will then look at the MBR's content to learn of the partition layout, OSX will look at the GPT layout.

That fact makes it possible to have even a different partition set seen under Windows compared to that seen under OSX! I've done this myself to make disks other than the internal boot disk work with as BootCamp volume, for instance, or to install a BootCamp partition on a disk that has already more than one HFS partition.

The only problem is to get this set up. Anyone feeling at home with MBR and GPT layouts can use my tool "iBored" for that. But maybe someone will one day also write a tool for the average user. (I'd do it if there was money in it, but I doubt it.)

Interesting info. I hadn't considered that you could have two partition tables for one disk.
I'll check out your app and do some research to learn more, but do you have any favorite resources for reading about partition tables?

Thanks.

Wikipedia has it all.
