Partition question [winXP]

Hey guys… my machine came with the HD partitioned into c: and d: … I would like to add a third small partition for Unix… I’ve tried to follow the directions given by MS, but I’m hitting a wall… basically I dont have any ‘unallocated’ disk space cuz it is all split between c and d

So, in order to create a third do I have to delete d: to free up some HD space, then make some of that space back into d: and the rest into my new partition x:??? Is that the correct way? I cant find any definitive answer from MS

THNX

Peace
