The machine runs currently the Elementary OS, I did connect sata m2 externally to this laptop-it recognized, I even formated the sata m2 drive to ext4, but once connectd sata m2 back to laptop slot, sata m2 was not recognised.
Actually I found newer bios file , but it is in .exe format, does that mean I have to update thebios through windows?
Bios file was here: https://www1.medion.de/downloads/index.pl?op=detail&id=18617&type=treiber&lang=uk
