The Perfect Server - CentOS 5.2 VMware Guest

[pg001]

I'm trying to follow the HowTo The Perfect Server - CentOS 5.2 making it as a virtual machine using VMWare. Here's the Specs of the Virtual Machine:

Allocated 20Gig harddisk space
Allocated 256 MB Memory
CentOS 5.2 installation DVD is an iso located in my server

I only get as far as the section where you choose your keyboard layout, because from that the setup is already different it looks like this already:



and when I click Next I get this error:



so I click Advance Storage Configuration and try to Add Drive


After that I get to this point and get stucked don't know what to do next...



Any help would greatly be appreciated. On the side note, I'm simply trying to install a base centos 5.2 server.
