Hi!
Just want give credit to a member @DelianM that has a workaround for junction failure in new deployment with latest ADK 10(2004) and MDT(6.3.8456.1000).
Good work @DelianM!
And all that has junction issue with ADK 10(2004) look at the workaround link below.
His change to ZTIDiskpart.wsf did the trick.
Best regards
