Lalaneta,
I used your post as a guide to make the appropriate changes in the registry using REGEDIT (from the search bar) with my original drive still installed. I then cloned my old drive using Macrium onto the new SN740 2TB drive. I had the new drive mounted in an enclosure that connects via USBC. Once the clone was complete, I placed the new SSD into the bay and everything works great. Very fast reads and writes, about 1.9TB of storage and a stable operating system. Fantastic!
