After the very timely death of my 2017 HP Envy (all Intel) laptop, I just managed to move the SATA SSD and the 16 GB RAM over to my daughter's retired 2017 HP Pavilion (Intel + Nvidia).
The Bluefin install I was using on the dead laptop booted right up and is working as if nothing happened.
FYI, this is my first time using Nvidia.
The old laptop had a spinning Win 10 drive and 12 GB of RAM (one 8GB stick, one 4GB -- who does that?? HP, I guess.)
