As a pre-requisite to MDT, you must install the latest Windows Assessment and Deployment Kit (ADK). Search Microsoft's site for the latest version and download it. Typically, you'll get a small app that lets you select components that are then downloaded and installed in the background. The components that you need are:

  • Deployment Tools
  • Windows Preinstallation Environment (Windows PE)
  • Imaging and Configuration Designer (ICD) [Windows 10 only]
  • User State Migration Tools (USMT)

It is highly suggested that you save the downloaded ADKSetup.exe file in a folder at the root of your MDTData disk (such as the \Install.MDT folder).
