WDS - Getting Multiple Images working

[Arcolite]

I've been using one image on my WDS server for a while now, but the time has come where I need to add a second image to the server.

My current image is fully unattended and uses a autounattend.xml to do all the tricks. The trouble I have is that the unattended file is on the main server config. If I try to attach it to the image itself I get a "This image version doesn't support adding an unattended setup file using this method" error.

This means that to use the other image, I have to tell the server which .xml to look at BEFORE I start to build those machines.

I'd like to be able to have multiple images, all with Unattended files which can be selected from the workstation via te PE Image Selection (which I have yet to see!) not the server.

Any ideas what I need to change?

Here is the unattended that is attached on the server...

If I take away all the unattended files I get the GUI to select the image on the clients, but it says there are no images available
