How do I split a Bootcamp Partition on a second drive? I have a Mac Mini Server 2011, which has 2 Hard disks of 750GB  each.
I want to install Windows 7 on the second disk, but i want to split this disk on two partitions: One of 450 GB for Windows and one of 300 GB with exFat to share data between Windows and OS X (is Lion by the way). 

I tried with the Bootcamp assistant, but it took for the Bootcamp partition the whole disk, and so I installed that way, but I prefer to have both partitions as I mentioned above.

Can I split it the way I want? I don't mind if I have to reinstall Windows as long as I have the best compatible solution for this.
Open Disk Utility and format second HDD with Partition Map Scheme to be Master Boot Record.
Then start up from Windows Install Disk by pressing Alt or C and create partitions from there.

You should probably use Bootcamp Assistant before (or after) just to save Windows drivers and Bootcamp taskbar utility to the flash disk or elsewhere.
