Hello,
I think I have a similar problem. New SSD Samsung 970 evo plus (m.2 NVME) is not recognized at BIOS level, even after changing different available options (secure boot, interl rapid, uefi on/off). It is seen at the Win10 installer, and the installation process can be finished successfuly (clean install). Although after restart no boot device is displayed (the only disk at laptop). So far I have used Samsung 950 pro 512GB (m.2 NVME), it worked with no issues at all.
Laptop: Clevo P771zm.
I would really appreciate the help
Regards,
Sławomir
