Following my thread about fitting an SSD to a new, well, boxed unused, Lenovo, I put W10 on the 2TB HD and gave up on the SSD idea. The original was very fast for a mechanical drive but I wanted the protection of a repairable/removable front end.
My pal tried the same with one of the mini Lenovos - with the same negative results.
We can not get into the BIOS as one could in't old days. It runs fine, but I want to have what I want, but not what some manufacturer dictates.
I never did follow the thread of one kind Ppruner who suggested certain ways of overcoming the limited BIOS controllability.
