I'm deploying Windows 8.1 via network boot using MDT on an external hard drive connected to computer to create a Windows To Go drive.
But the step in my task sequence "Install Operating System" takes a lot of time (+ 45 min).
I tried to do the same deployment on the internal drive and the same step takes only 5 min.
I tried to add USB 3 drivers in LiteTouchPE because the external hard drive is USB 3. But it is still very slow, I don't know if the drivers where correctly installed.
Or is it something else ?
