To start off, the problem I'm addressing is that the MDT format and partition action wipes the entire disk, including ImageSafe data used by ZENworks 10. So I began the task of a custom action that does not wipe the drive and repartition. Instead, I wrote a script that should search for the bootable partition and set the DestinationDisk and DestinationPartition properties. However, in testing, the Windows 7 setup stops and asks "where do you want to install windows". Does anyone have any advice on how to address the initial problem or two how to make the script function correctly? Script UWWOSDestination.zip
