How To Create Partition In Fc5

Hi sir,
I want ask you something,
i have Fedora Core 5 installed and i wanted to install windows NT at same machine (laptop),
currently i have only this partition

[mani@C03KLJ76 ~]$ df -k
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
27234172 22826824 3001604 89% /
/dev/hda1 101086 14576 81291 16% /boot
tmpfs 253856 0 253856 0% /dev/shm

So how can i do that?
Can anyone guide me please
Basicly i want 2 OS in same machine

Many Thanks

base on my experience first made 2 partitions on my HD using the diskmanager 2nd i installed windows OS on the first partition and on the 2nd partition install the FC5...you have to install first the windows os....or you can use VMware
