Partition Question

I am in the middle of my first experience at partioning a hard drive. My hard drive is 20gb. I am using Partition Magic 7.0. My primary OS is XP. I want to use Linux Red Hat 6.2 on the partition. I seem to have successfully created the partition as I am able to see a graph of it. Also I have been able to resize the partition to allow XP operate smoothly.

Here’s the problem. I don’t see a “D” drive in My Computer as I thought there would be with a partitioned drive. I have tried to use the boot disk that came with the Red Hat package to help get things going without success.

What am I doing wrong? Please help.
