I am using
MDT 2012 Update 1. Attempting to Deploy 2012 DC to a VM, run windows updates, and then sysprep/capture that image. This is the same task sequence process I have used for Windows 7 / 2008 R2 and it works fine.
However, for 2012 DC it deploys the image, starts running/installing updates and then runs sysprep and on reboot it goes to a
"Choose an option" screen if I choose
"Exit and continue to Windows Server 2012" it reboots and goes back to same screen.
