I recently bought a 7780 and the first thing I did was image the original disk before doing a clean windows 11 install. I ended up going back to the original image because I couldn't get the clean installation properly configured 100%. Everything seemed ok, all devices had the proper drivers installed that I got from the dell website using my service tag, but I just couldn't get this one application in a VirtualBox VM to work, the app only runs on Windows 7 with a USB dongle for security and it just wouldn't work until I restored the original Dell Windows 11 image. It was the weirdest thing, I've been running the VM and application for years using various PCs and the only time it wouldn't run was with a clean windows install on my Precision 7780. So you might want to install the Dell specific windows version to avoid any problems down the line.
