Autounattend.XML Problem

Hello; Please Help; I created a autounattend.xml file using Windows System
Image Manager. Each time the files runs, it stop at point where you create
or select a partition. If I click on ok, it then stops with the error
message: Windows could not prepare the computer to boot into the next phase
of installation.

The logical drive is Raid 1. Below is a copy of the Autounattend.xml file.
