Good Morning! Since I believe to have my OSD TS's set up the way I want them, I'm looking to add a couple of features. I've been looking at Niall's HTA here as well as a few others like this that may provide prompts for OU. As far as Niall's I'm about done with the prerequisites, but don't see a place in his screenshots to prompt for an OU. Due to these OSD TS's being used by so many departments in my company, it's a must have. Therefore, I found the other one (link above) which says it will prompt for an OU after easy setup. I followed the instructions except for the end where I was a little lost. I know how to mount and edit an image, but which boot.wim file do I do it to and do I do this before or after I create the Boot Image package? I looked in one of my MDT boot image packages and it only had one WIM file - it wasn't boot.wim, though. What do you think? Thanks! Ben K.
