I had cloned my Samsung 840 SSD (Windows 10) to a Samsung 960 EVO. The BIOS from Asrock Z77 Extreme6 has been flashed to 2.90, which supports NVMe. In the BIOS settings, I have set the NVMe SSD as boot #1. However, the BIOS is not detecting Windows 10 on the 960 SSD. I tried doing bootrec to fix the mbr and what not, but still get the same message "Reboot and select proper boot device." Any ideas?
