Start by selecting New-PEBuildTask and select the Recovery tab. Keep the Task Name simple, and remember Recovery will be automatically added as a Task Name prefix.

This task will use WinRE.wim to create Recovery Media.

You also have the option to include -AutoExtraFiles and set the -ScratchSpace. The default Scratch Space for WinPE is 32MB, but if you do not select an option (since this is not a Mandatory parameter), this will automatically be set to 128MB.

You will be prompted to select an OSMedia to use for the Task. By design, if you entered a Windows Version in the Task Name (1803, 1809) you will only be shown OSMedia that matches that Windows Version.

WinPE Additional Content

If you have added WinPE Content to OSBuilder (DaRT, Drivers, Extra Files, ADK Package), you will be able to select them to complete the Task.

Complete Task

Once the Task is complete, you can use New-PEBuild to build the Recovery Media
