We have successfully created an WIM image file using imagex on a PE boot CD. Also, we did create an AutoUnattend.xml answer file using the Windows Automated Installation Kit and trying to get a Windows 7 image applied to a test system. We are consistently getting this error upon first boot on the test system:
"Windows could not parse or process the unattend answer file for pass [specialize]. A component or non-list setting is specified more than once in the answer file."
This appears just as the "Setup is preparing your computer for first use" message appears. We see nothing duplicated in the <specialize> data and not sure where to start on this.
