Hi Fernando,

I'm aware this is a Windows forum, but I was looking for confirmation that at least the BIOS flash was most likely not the issue.
I know that Ubuntu 18.04 works with NVMe natively, because I recently installed it on a different machine but also with a Samsung NVMe SSD.

Anyway, your comment made me realise that I probably didn't install Ubuntu to boot in EUFI mode.
I've rechecked all BIOS settings and made sure to (re)install Ubuntu in EUFI mode, and it boots now!
I could not have done this without your info, so thanks again!

1. What lets you be sure, that the insertion and the flash of the modded BIOS was successful? Did you see a Disk Drive named "PATA_SS" within the BIOS thereafter?
2. Why did you dsable the SATA ports instead of unplugging the connected drives?
3. Why couldn't you install Windows onto the NVMe SSD? Has it not been detected by the Win10 Setup or did you get any error message?

Hey guys,

New to this BIOS modding and all, though I'm decently well versed in computers Anyways,
I have an Asus ROG GL552VW laptop. I bought a 256gb NVMe M.2 SSD to install, hopping I'd be able to mod the bios. I injected the NVMe module properly using the UEFI tool, then I tried updating the BIOS to it, using "WinFlash /nodate" through the CMD command and did the delete the old file and replace it with the modded one trick. BIOS updated. But I still can't see the SSD anywhere, not in the BIOS, disk management, or anywhere in Windows 10. I either didn't insert the NVMe module properly, or I didn't replace the BIOS with the modded one properly, as I kept getting "Invalid BIOS file" or "BIOS file too old" or both. Any help? I spent a couple hours on this yesterday to no avail, kind of frustrating and I want to use this drive. EDIT: Just attached my modded BIOS, which I named the same as the actual BIOS. Thanks!

Hey Fernando, thanks for the response!

Asus technical support and many people in other forums tell my this laptop does NOT support NVMe, only SATA SSD. I am trying to install windows via the Clover method on the SSD since I can't get this to work.

@Ace:
Note that NVMe is a logical interface specification while M.2 is a physical form factor and connector specification. Although the NVMe specification allows for other buses it is predominantly implemented over PCIe.

M.2 connectors can have support for a wide variety buses, PCIe and SATA being most widely available. Devices usually support only one of these while motherboards may have support for both or only one of these.

Unfortunately your laptop's M.2 connector seems to only support SATA that makes the connection incompatible with NVMe.

Your laptop's motherboard most likely has PCIe connectors, so if you really are determined, you should be able to connect your NVMe SSD to your laptop's motherboard. You however may need to remove a PCIe expansion card, such as a WiFi adapter, if you have no free PCIe connectors.

Note that converter cables and cards exist between the various connectors and form factors of PCIe. Also note that PCIe splitters exist too (also called PCIe bifurcation) but that requires motherboard support, an unfortunately I don't know whether your motherboard has support for that.

1. There is no option for secure boot in the BIOS settings.

2. I installed Win 10 to it using the Clover bootloader prior to trying to mod the BIOS, and went back to using that after the modded BIOS failed to work. It's in the computer now.

3.
Here's the BIOS.

This is an inexpensive motherboard that a friend gave me, and I use it for a computer connected to my television. It works very well with the Clover/USB drive method of booting to the M.2 drive, so it won't be a big deal if I cannot get it work without one. I had a regular SSD in it, but I wanted to use that for a computer I was giving my cousin. I reasoned that since it was a relatively late model board with a UEFI BIOS and a free PCIe X16 slot, that an M.2 drive on a PCIe card would work fine. I was wrong.

@Fignon:
Your UEFI BIOS is a decent one, does not seem to be a cheap one. Unfortunately however it seems to be a very early UEFI BIOS that is less UEFI friendly than later UEFI BIOSes.

Could you please use NvmExpressDxe_4 instead of NvmExpressDxe_Small so that you can see the NVMe SSD model name displayed in the booth menu. You have plenty of free space in your UEFI BIOS image.

You need to boot the Windows 10 installer in UEFI mode so that it installs Windows 10 in UEFI mode. For that you need to manually select the boot item that starts with "UEFI:" and is your USB drive.

Assuming that you have previously correctly installed Windows 10 in UEFI mode, but need Clover to boot, you should be able to boot it from UEFI Shell. And if you use EFI\Boot\bootx64.efi that should even create a boot menu item for Windows Boot Manager.

Please launch the "Built-in EFI Shell" from the exit menu.

Then you need to find your boot drive:

fs0:
EFI\Boot\bootx64.efi
fs1:
EFI\Boot\bootx64.efi
...
 

You need to iterate on the "fs" numbers until you find the EFI System Partition and Windows 10 starts.

If for any reason something else starts then you need get back to UEFI BIOS and EFI Shell and continue trying with the next "fs" number until you find Windows 10.

Note that file name completion using the Tab key works in the EFI Shell.

This worked!
You left out one command, but I would never have found the answer if you hadn't shown the way. It was:
FS1:
CD EFI\BOOT
EFI\Boot> bootx64.efi

Once I did that, it booted right into Windows 10. On reboot, the boot screen now looks like this:


I did insert the NvmExpressDxe_4 module and flash that first, so I don't know if that made a difference. But I've rebooted it repeatedly, and it works fine! Thanks.

Hello guys,

i went thru your forum and I have some kind of the same issue with my Asus R702UV-BX106T (the motherboard is actually the Asus X705UV model), notebook I got brand new last year 2017.
I bought the Samsung 960 EVO NVMe 256Go since there is a M.2 slot there (see picture attached).
Problem is the SSD is not found, neither in the BIOS, neither in Windows 10.
The original BIOS version is X705UVAS.304 (see file attached).
I tried by upgrading it to the newest version 309. But still, SSD was not found :(
Then I tried by modding the BIOS as you explain in the forum, but still didn't work : EZ flash or Winflash recognize the mod BIOS as an "incorrect" one.
Well, I downgraded the BIOS to the original version 304.
Finally, I contacted ASUS support and they replied to me this motherboard doesn't support NVMe SSD. They gave me the following list of tested SSD for the X705UV notebook :

- 128 G :
HYNIX/HFS128G39TND-N210A
SANDISK/SD8SN8U-128G-1002

- 256 G :
MICRON/MTFDDAV256TBN-1AR1ZABYY
HYNIX/HFS256G39TND-N210A

- 512 G :
MICRON/MTFDDAV512TBN-1AR1ZABYY
/SANDISK/SD8SN8U-512G-1002

Indeed, all these SSD are M.2 SATA III and not NVMe.

i dunno if you guys can help me ?
I don't know what to do next, unless last option is to get refund on the Samsung 960 EVO :(((
But I'm sure there has to be a solution :D

Thanks
Nico
