I have recently purchased the NUC5i5RYH, and assembled - SSD SanDisk Ultra Plus 256GB SSD #SDSSDHP-256G-G25.
Unfortunately, the hard drive is not recognized by the NUC, even in the bios stage.
I have updated the bios version to the newest version but with no change regrading the hard drive.
Have you tried testing your NUC with a different SSD?
