Not long ago I was using MDT 2013 to develop a few images.  Deploying from the server, whether booting from PXE, CD/DVD, or a USB drive worked fine.  However, when I created a stand-alone ISO and extracted it to a bootable USB Hard Drive, the image deployment failed with the following error:

Script not found
Unable to find LiteTouch.wsf needed to continue the deployment.

The error didn’t occur if I used the same ISO attached to a Hyper-V guest.

As I investigated I noticed that both the _SMSTaskSequence and MININT folders were not on the OSDrive, but on the USB drive.  I found a few forum posts and blogs that offered DISKPART CLEAN as an option but this didn’t resolve my issue.
