I have my MDT deployment configured to install applications in the "Postinstall" section. A clean OS gets imaged, applications get installed. It works, with one snag. It boots into the OS, installs all the applications, then when it's done, I get"The task sequence has been suspended. LiteTouch is trying to install applications. This cannot be performed in Windows PE..."
It's not in Windows PE though. This is happening in the OS after it's been installed. The applications are getting successfully installed before the error message shows up. Everything finishes if I manually reboot, no errors, no warnings. But why is the process getting hung up and requiring manual intervention over something that's not true? I've read other posts where people say they needed to "clear" the partitions. I booted into a GParted Live USB and completely destroyed the partition table. This isn't leftover from some other installation. This thing is in the OS thinking it's in PE and it can't do what it's already done.
