Hi there. Yesterday I used Deployment Image Servicing and Management Tool (DISM) to add drivers to an untouched SP1-U x86 ISO from digital river. After that, Windows failed to start, because of driver corruption. It had nothing to do with the specific drivers I integrated, I checked it with many drivers. In all cases, I was getting the same error message. I am downloading a SP1 ISO (without the -U) to see if problems persist. Have you ever experienced a similar issue?
