Help!

I have 2 Hard Drives, 1 is a 4gb for windows and the other one I want to split partition.

20gb for Linux Fedora Core 2
20gb for Windows

I know how to partition the 40gb harddrive for just Linux, but I dont know how to set up the partition to split it as mentioned above.

Help ASAP since I just started to run the Fedora Core Installation.
