Recommendation 1: Use a VM for this. It's essentially a giant C.F. to do this with native booting, and is potentially fragile.
But if you're going to ignore that and do this anyway, realizing that it can break anytime in particular with OS upgrades, and that it's very difficult to impossible to resize the three volumes once you've installed the systems:
1. create three partitions, setting each to be the size for OS X copy 1, copy 2, and Windows respectively. The Windows partition needs to be set to MS-DOS format (actually FAT32) which later in the Windows installer you'll reformat as NTFS. Do not use Boot Camp Assistant to resize/partition the disk, it simply won't work for this use case.
2. install OS X copy 1
3. install OS X copy 3
4. Use gdisk (available at sourceforge) which is a command line only application, to create a new hybrid MBR adding only the last partition (Windows) to the hybrid MBR and setting it to be bootable. As a concequence you will not be able to see/share either OS X volume from within Windows. The Windows NTFS volume will be visible from within OS X.
5. Install Windows to the only partition its installer should see (confirm size), you'll need to format it NTFS first, and I suggest using the fast format option if available.
