One of the task for this summer is to replace old XP 2020 PC and have purchased some Dell i3 desktops. We created a Windows7 sp1pro 64 build disk before the upgrade and successfully built one of the new Dell PC. Now we have tried to build several Pc only for it to freeze at the loading drivers stage. We built a new specific Dell desktop Rebuild disk but with the same result. We have a CC4.5 2012 R2 Server just upgraded Any further ideas would be appreciated.
