My PC has a single drive, with currently two partitions, Win7 x86 and Data, plus two other (OEM and system-reserved)

I want to create a third partition to install Win7 x64, but the installer didn't like the fact that partitions were dynamic. I don't know if there's a way to recreate basic partitions, and make my data partition dynamic, since I read that I can have 4 basic partitions? I have GParted liveCD, but before I'd prefer to ask here what is the best partitionning option.

Thanks for your answer! I used Magic Partition Manager from MiniTools, it did the conversion for the same price and does partition management. – CharlesB Sep 13 '10 at 15:07

GParted didn't help, but I was able to convert partitions from dynamic to basic with Magic Partition Manager from MiniTools (29 USD). Then I recreated partition and I could install Windows on it.
