Performing Staged Deployments Using MDT (OEM Preload)
In many organizations, computers are loaded with the operating system image before deployment to the production network. In some instances, loading the operating system image is performed by a team within the organization that is responsible for building the computers in a staging environment. In other instances, loading the operating system image is performed by the computer hardware vendor, also known as an original equipment manufacturer (OEM).
Note The OEM preload process is supported in MDT only for deployments performed using LTI. For Configuration Manager 2012 and Configuration Manager 2007 R3, use the prestaged media feature.
