I’m using the Ultra II 240GB drive. I originally installed the drive into a SATA 2 port and cloned my 1 TB drive which contained windows 10 - 32 bit, everything worked fine. I then relinstalled windows 10 - 64 bit and again everything worked fine. The Sandisk dashboard showed I was only connected at 3 GBps, so I switched SSD drive to the only SATA 3.0 port and moved the 1 TB seagate drive to the SATA 2.0 port. I booted the system making sure the boot sequence was correct with the SSD booting first, but windows nevers starts. I see the Lenovo splash screen then the computer shuts down.
I have a Lenovo M82 tower computer.
