Thanks for the fast reply Fernando, I used your tutorial to add the nvme driver into the bios, as that's how I used the laptop with the Plextor M8se(G) drive for a while. But the 970 is seen in the windows 10 installation, but not detected as windows boot manager after the first restart of the installation. After some research I saw on your other tutorials, a bunch of files including ubu and many other nvme files to inject into the bios, which I think will help the laptop see the 970 evo as bootable. Any idea ? Thanks again.

This bios doesn't have Fast Boot option, and by disabling and enabling Secure boot, nothing changes. From what I saw earlier, while trying to install a windows 10 on a hard drive with the 970 evo inserted, the bios wouldn't see the drive as windows boot manager either. After I took out the 970 evo from the laptop and a restart, the bios instantly detected the hard drive, so I am implied to think that there is a compatibility issue somewhere between the module in bios (that's why I was asking about a updated mod if there is one, or a separate module for samsung drives) or something. I can't explain. I did rebuild now the bios with more mods inserted with MMTool, and hopefully that will fix the issue...

As it was seen on the windows installation, I can say it is seen by the laptop. The ssd will not be seen in the bios (as the plextor one wasn't either and it was working flawlessly), so the nvme not being inserted correctly drops. The only way to see a ssd in the bios would be to add a AHCI ssd (XP941 which I had in the past installed), and that will trigger a AHCI drives available in the bios.

Ok. So I did find the issue. It was as I thought about to be the issue. I added one mod for samsung nvme drives and did updated the bios rom with ubu too, and the drive was successfully seen as a windows boot manager in the bios. Thanks a lot for the time spent! Have a nice day!

Ok, so I re-downloaded the latest bios for the laptop again, used MMTool to add the two following modules: the one from the OP from your guide (NvmExpressDxe_4.ffs more specifically), and downloaded the package from here (link removed by Fernando) and from the modules folder, I added the Samsung_M2_DXE.ffs, then introduced the bios in UBU tool. That did the trick, and the 970 evo is working fine (actually now installing the drivers as speaking).

As I said, the ssd is not being displayed in the bios, as it is very very simple (not UEFI interface), but legacy interface. The only drives shown are the two hdd's and the dvd-writer. Thanks for the time, and if I can help with additional info, I am glad to do it.

EDIT by Fernando: The download link has been removed, because the related package contained the AMI UEFI MMTool v5.0.0.7. Such links are forbidden by AMI.

That's what I don't understand, the bios was flashed 1 year ago with only the NvmExpressDxe_4 module injected and it worked flawlessly with the Plextor NVME drive before. And the 970 evo was incompatible in some way that it wouldn't be booted from. Something needs to be there that did the trick.

Following the other post, thank's to @Fernando for support.
here is my modded bios with your NVMe module.

Still have flash error for wrong Bios file size in Afuwinx64

I have had that problem. I did these steps: https://www.youtube.com/watch?v=DwJS8-GTgRU and worked flawlessly over dos with a bootable usb stick.
