Sharkpup65 The idea is to try to perform the Windows install offline, not with the computer off. Please read the instructions in the guides I linked.
And then the idea is to keep the computer offline, if possible, thereby not allowing Windows to download what it thinks are suitable drivers, because you'll install the correct drivers yourself. You'd do that by downloading them (but not installing) on the old laptop, then transferring the downloads to the new laptop, via USB, and running the installers.
If you're still not sure what to do, there are plenty of video tutorials out there. I don't have a particular favorite because I prefer written instructions, but it's easy to find a channel with a lot of subscribers or that's connected to a reputable company and just follow along. Dell probably has instructions somewhere on its site, but then so do most other laptop manufacturers.
