Cannot partition HDD with PM 8 correctly, HELP!

[jrmints]

Okay here's the problem, I just downloaded FC 5 onto a DVD and have used osloader2000 to boot from the CD/DVD drive. So far I have been able to bring up the FC 5 instillation screen and have gotten up to partitioning. I am trying to make this a dual boot computer with my Windows XP pro, but I cannot seem to partition it correctly. I have been using Partition Magic 8 and have created partitions, but when the computer restarts the partition does not go through and I can neither view it during FC 5 instillation nor in Windows. Is there a proper way to partition using PM 8 or would it be easier to partition during the FC 5 instillation, and if so how? Please help, thanks
