The error was: The task sequence has been suspended.
LiteTouch has encountered and Environment Error (Boot into WinPE)
I had a strange problem with MDT. When I booted the in WinPE.
Rebooting and again started the WinPE image did nothing same error again.
Solution is very simple.
You have to remove two directory’s C:\_SMSTaskSequence\nul and C:\MININT
After that you can resume deploying the OS TaskSequence you want.
For sure I cleaned the Disk with Diskpart.
