Hello, I am having the same stopping point as you have in the post. I noticed no one responded to you. I wanted to find out if you found a fix for this yet? I sure could use the help. I am using MDT and Hyper V but I am pretty sure the fix is the same. I am thinking it may have something to do with the account (MDT) or local admin account one used in the Rules section and Boot.ini settings but so far I have not had any luck.
