WDS Unattened Disk Settings

Question

I am struggling to get my WDS answer file to delete the existing disk partition, re-create it and install the os to it. I'm installing windows 7. All my other settings are working fine, its just this i'm struggling with.

I'm also a bit confused as to which unattended file to put the disk setting in, does it need to go in the client xml file or the image one? This is the setting i have tried that is having no effect.

This post is a little old, however if you still need help or to help others in this situation...

Download and install the Microsoft Deployment Toolkit (MDT)(it's free). MDT will integrate with WDS and will make many things easier. In particular, once you have setup a task sequence for your deployment, open the task and go to the Task Sequence tab, then navigate to the Preinstall section, and open the New Computer Only section and you will see the settings to Format and Partition the hard drive. MDT has already set it to format and partition for you. More information on MDT can be found on the MDT page on TechNet.
