We have a MDT 2013 server setup and working.
Now, for each machine in deployment share, an USB is also created, (One "computer" stored on one USB stick)
Got it working in this question, thanks :)
Upon deploying to a target machine from USB, the dialog is not identical to what it looks like using PXE boot.
When booting from USB this happens:
-Domain or WORKGROUP must be selected, that selection not available during PXE boot.
-Language/keyboard can be selected, those selections are grayed out using PXE boot. Only timezone is selectable then.
-The option to not set administrator password at this time is not present, it is using PXE.
The MDT->Advanced Settings->Media folder is pointing to the same task sequence as is used for the same image in PXE.
The system deployed is a custom Win 2012 server.
