Add HFS-Partition after Parallels/Bootcamp-Installation

Hey guys!

I had some trouble installing Parallels with my Bootcamp-Partition so I uninstalled everything, started over new and finally got it working!

My configuration:
Mac Pro 2x2.66 GHz Intel Xeon with 4 GB RAM
Mac OS X 10.5.1 running
Parallels Desktop 3.0 for Mac Build 5582
and Boot Camp Windows XP SP2

So far so good, it really seems to be working quite well.

Now, here's my problem: My Mac OSX partition is about 370 GB big. I'd like to split that into two partitions one with 270 and the other with 100 GBs. I know that Bootcamp has trouble with more than two partitions though. And I'm not really sure what's going to happen to my Parallels Bootcamp-VM if I just add a partition in my hdd utility!

Can you tell me if that's going to work with no problem or whether or not I have to edit something before adding a new partition?! Thank you so much for your information!

Greets,
Oli
