I recently bought a 500gb Samsung 860 EVO and was having a difficult time getting the OS from my HDD to the SSD. Samsung Magician doesn't seem to be able to migrate the OS so I followed this tutorial, I transferred all the data, then set the SSD to my boot drive in bios but I keep getting an error saying "Reboot and Select proper Boot device". If someone knows how to fix this error or a better way to migrate my data and OS I would be very grateful, thanks.
