Trying to partition a Boot Camp partitioned drive

[simkhai]

I am trying to create a new mac partition on a hard drive I have already partitioned using Boot Camp. When I try to do that I get this error message:
The disk appears to be partitioned for Boot Camp. The proposed changes may make this disk using Windows unbootable."

How can I partition it so I wont do anything harmful to the Windows partition?

Thanks

I have never done this before but there are a few guides out there, but I'm not sure how good they are

Of course make sure you have backups before starting anything.
