I never did get an SSD to work in my Lenovo PC. Pity, a fast machine, even if built out of tinsel.
I too will lose my W10 if I am not careful since I upgraded it from 8.1 free.
It ran well on the 2TB drive but I did want that SSD front end. A pal spent hours trying the same thing and went out and bought a hi end load of bits with an Asus board. Funnily enough, that MB failed. The local dealer put him right.
Anyway, I can open my W10 via my MS account, but if I want to sell it (I do) I'd like a proper Key.
I'll try again shortly.
