I have a MDT light touch server(OS 2008 r2 with Hyper-V) that was upgraded from MDT 2010 to MDT 2012. After the upgrade all of the task sequences fail. They start and I get the blue Microsoft screen but then get a command window and all processing stops. I don't get the Welcome screen. I can't find any logs. I have rebuilt the boot .iso. Does any one have a guess what might be wrong?
