You do not have to use the vRealize Automation PEBuilder to create your WinPE. However, if you do not use the PEBuilder you must manually insert the vRealize Automation guest agent into your WinPE image.
Before you begin
Select a Windows system from which the staging area you prepared is accessible and on which .NET 4.5 and Windows Automated Installation Kit (AIK) for Windows 7 (including WinPE 3.0) are installed.
Create a WinPE.
