CentOS Installer make ONE partition

I have tried to install CentOS 6.4 twice now, and it has messed it up twice. Both times I installed it, it setup my harddrive like this: http://gyazo.com/156ab5539eeac09b6785b211f6482c72. I want EVERYTHING to be on ONE partition, like my server came. At this screen, I have tried use all space, and remove existing Linux : http://www.techotopia.com/images/f/f9/Centos6_installallation_allocate_space.png

Use the "Create a custom layout" and just make the partitions yourself. I had to do an install yesterday with the exact configuration, and the custom layout was the only one that worked. Just make a small swap partition and the rest mounted as "/".
