G771JW BIOS not detecting (NVME) M.2 SSD Samsung 960 EVO 250GB

Hi there,

I've just installed a Samsung EVO 960 (250GB) PCIe SSD on the M.2 slot of my G771JW and installed Windows 10 on it using a USB Win 10 installation. Up to here, everything fine, the installer detected correctly the SSD, partitioned it and installed Win10 in less than 3 minutes. The problem comes when re-booting: the BIOS (UEFI mode) is unable to detect the SSD.

I've read quite a lot about this issue and tried all possible BIOS configuration but nothing seems to work. The BIOS never detects the SSD and therefore it is unable to boot from it.

Is the G771JW SSD boot compatible? Should I give up with the 960 EVO and try previous Samsung models (950?)? Is there something I'm not taking into account?

Thanks for your help.

Is the latest v211 BIOS revision installed?

Yes it is.

After a lot of Google-ing I've found the problem.

The G771 and G751 BIOS (Up to v211) only support booting from an SSD M.2 AHCI but not from an M.2 NVMe. The 960 EVO is NVMe and that's why the BIOS is not detecting it.

I'll need to use an SM951 which is AHCI, but Samsung no longer sells them and they're out of stock.

If you can make do w/ a 128GB drive, Newegg has the SM951 (AHCI) in stock for only $104.22...

Try to raise the LLC in bios. Worked for me with level 7 on a 6850k

Hi. G771JW perfectly works with NVME SSD.
You can mod your BIOS for support NVME SSD.

I am using this instructions:

Which SSD did you install on the system?
Can you do speedtests of your SSD?
