Partition XP drives on Mac...please reply soon

Hi all, Well i have installed XP on MACBOOK PRO and its running fine. But in XP i have only one drive of 120 gb and i want it to partition into three drives C: D: and E: drive of 40 gb each. For this i tried to install Partition Magic 8 but it isn't starting and it is giving the following error:-

"Error 117: "Partition's drive letter cannot be identified"

and I even tried Acronis Disk Director and it is giving the error :-

"Unsupported hard diskdrives. Acronis Disk Director does not support windows on dynamic disks, EZ-Drives etc. ".

So please give me any solution to partition drives in XP. Thanks in advance.

Why the obsession with partitioning drives?

I get why it made sense back in the Windows 95 days, but now?
Short answer: From what I've read it's fairly tricky, but I'd imagine if you can find a tool that lets you boot off a CD and then repartition it might be doable.

Part of the reason you're having trouble is that your MacBook Pro uses EFI instead of BIOS. EFI works with the MBR differently than normal BIOS, so utilities like Acronis don't work properly.
