The fix posted by rc00451 worked for me. Thank you for that post. I have spent two days troubleshooting all sorts of things and would never have looked at that (or known to look at it.) What is strange is that the default winpe.wim (and BCD) must have that setting configured to ignore the DEP setting in the BIOS because my initial test build worked on everything I booted without a problem. I made a new .wim adding in the WMI, HTA and scripting packages and almost everything would boot except for the DC7800 SFF and the DC7800 UltraSlim. So, of course I spent all of my time troubleshooting the package build process and wondering if I had missed a critical formatting procedure for the USB. Thanks again.
