Hi all, I'm having the exact same problem with the "Found new hardware" wizard. I'll provide you guy's some extra info on my specific problems that might help us out. I'm preparing an Unattended Installation for a company. Before I used the silent install option for driver support. After adding support for a couple of different types of machines some of the drivers wouldn't install properly anymore. I'm now using the OemPnPDriversPath variable in winnt.sif which works fine. The UA is supporting several types of Dell desktops and laptops (GX270, GX280, D600 and D610). After adding the drivers for the X1 (a new model, very light) my installation comes up with the unwanted wizard. My guess is that when the video driver (Dell driver, Intel Graphics Video v6.14.10.3943, A02) is being installed, Windows will be triggered to start the FNH wizard. I don't think it has anything to do with the winnt.sif or anything else in the unattended process but more likely in the driver. The reason for that is I didn't provide any display drivers at all for none of the supported types and they work fine. Normally undetected hardware will just show up with a yellow exclamation mark. Cheers, Michiel. BTW The driver mentioned above was an MSI setup. I used MaSaI to extract the .inf and .cat files and added those to my OemPnPDriversPath. Driver installs fine.
