Install the ADK and Import it into Boot Disk Creator.
Before imaging it is necessary to install a Preboot Environment, usually Windows PE. Windows PE is part of the Windows Assessment and Deployment Kit. (ADK)
For Ghost Solution Suite 3.X it is suggested to use Windows PE 10. Here are the steps to install and import the ADK: http://www.symantec.com/docs/HOWTO124277 - Ghost will not allow the import of an unsupported WinPE version, so check the release notes prior to downloading. The currently supported WinPE version for GSS 3.3 was shipped with Windows 10 ADK v 1709. GSS 3.3 RU1 adds support for later versions.
