You can create the master image in either of these ways:
In Windows, by using Management Agent installed on the master machine. This type of imaging is called online imaging.
By using a bootable media (either Acronis media or WinPE-based media) with Master Image Creator, or by using the command-line utility in a WinPE-based bootable media. This type of imaging is called offline imaging.
This section describes imaging with Management Agent and Master Image Creator. For information about imaging in the command-line mode, see “Command-line mode and scripting under WinPE”.
