@gicode38enibe:
Your motherboard most likely has an M.2 connector that has no support for PCIe while your NVMe SSD needs to be connected to the PCIe bus. Unfortunately you cannot fix this by software changes, including UEFI BIOS modification.

You might however be able to make it work if you find an PCIe connector on your motherboard, Mini PCI Express most likely, and connect your NVMe SSD using a Mini PCI Express to M.2 adapter.

Alternatively, there are USB 3.0 to M.2 PCIe adapters, I'm not sure however whether your motherboard has support for USB 3.0 or whether you can find an internal USB 3.0 connector so that the NVMe SSD could remain inside the case.

For more information please see my recent comment on M.2 vs. NVMe that is fully explaining your situation.

Hi Fernando,
thanks for your quick feedback.
i'm curious to know how you get the info my M.2 port is only designed for SATA (then AHCI) SSD. Apart from Asus support answer.
Sorry to ask u that but I like to understand what's going on :)

Well, looks like I'm gonna go for the Crucial MX500 M.2 2280 - 250 Go or the Samsung Serie 860 EVO M.2 - 250 GO.

Both are quite similar. The Crucial is cheaper...

Thanks again for your help ;
Cheers

Well you won lol

I like computers and stuff but I didn't know last SSD technologies were so messy. I mean I wasn't aware of all this before I got stuck with it :/
I had just checked the M.2 port "design" and nothing more.
Next time, I will triple check :D

Thanks again!

@Fernando I was using UBU to update some things in my stock BIOS 3801 for my Rampage V Extreme BEFORE I added the NVMe EFI file you mentioned and noticed something. UBU reports that it "Found EFI AMI NVMe Driver GUID 634E8DB5-C432-43BE-A653-9CA2922CC458" in the stock BIOS already? Do I even need to add the one you mentioned?

Hello,
I have Asus P9X79 DELUXE motherboard. I've bought Samsung SSD 960 PRO 512GB M.2 PCIe disk, then I realized that my BIOS won't detect it. I have updated my BIOS with Guide from first post, Fernando thank You for all your help :) Then I have installed Windows 10 Pro. At first everything seems allright, but from time to time, every around 5, 6 days I have BSOD (Blue Screen Of Death).

My system:
Windows 10 PRO,
Motherboard: Asus P9X79 DELUXE
CPU: Intel Core i7 3930K 3,20 GHz third gen.
GPU: Gigabyte GeForce GTX 780 3GB DDR5 PCI-E NVIDIA
memory: Corsair DDR3 8 x 8GB 1866 MGHz (64 GB)
power: Corsair 1200W ATX

BSODs messages:
1. MEMORY_MANAGEMENT
2. PAGE_FAULT_IN_NONPAGED_AREA
3. NTFS.sys
4. FAULTY_HARDWARE_CORRUPTED_PAGE
5. MULTIPLE_IRP_COMPLETE_REQUESTS

Dear Fernando, I hope that You could help me. Please tell me what should I do :)

Thank You for quick answer :) I have photos of BSODs, I've watched them but unfortunatelly no one of them have number of errors - only advise to contact to technical help and name of error which I wrote on my last post.
I have tried BlueScreenView program to see more detalis - it show me 1 error, maybe it could be helpful?

Hi Fernando,

great tutorial! However, I don't seem to be able to boot from my NVMe ssd. I followed the instructions and got the drive to show up as PSATA in UFEI bios. However, when I select it as a boot drive I get the 'no bootable device' message. I'm on Win 7 Ultimate 64 (SP1) with the NVMe hotfix (KB2990941) - the drive works just fine as a storage drive. I did a system clone w. the hotfix installed using AOMEI partition assistant to the NVMe drive. The drive uses GPT, I have an UEFI bios, I've turned off secure boot, and tried different settings in CSM (including turning it off). No need to say I cloned my existing Win 7 instead of a clean install. NOTE: in bios it does say ASUS UEFI bios, not AMI bios.

Setup:

- Asus M5A97 R2.0 mobo (latest bios w. mod)
- AMD FX 8320E cpu
- WD black PCIe 512 GB NVMe drive (connected thru Uptech PCI140 m.2 adapter)

Thanks - Bill

Thanks for the quick reply Dieter.

Reinstalling the OS is not really an option - I don't keep any data on my sys drive but over the years it has grown to over 400 GB (essential programs and games) - having to reinstall everything plus updates would probably take a week or longer.

Just a thought - if I downgraded to win 10 and then cloned to nvme might that work (native NVMe support)? The thought makes my skin crawl since I'm no fan of win 10.

Thanks again - Bill.

@bill_boots:
Since you already have a GPT disk, you only need to create an EFI system partition:
- See Method 2 (using diskpart and bcdboot) in https://www.easeus.com/partition-master/...ows-10-8-7.html
- You need to use "create partition efi size=100" instead of no size (as in the text) or 260 (as on the screenshot) so that you get the same size as a default installation
- You should be able to simply run these tools in an Administrator command prompt without having to boot from the installation media
- You need to shrink one of your partitions to have unallocated space for the new EFI system partition

Alternatively, this should result in working UEFI installation of Windows too:
- Install a new Windows instance of the same version to the new and empty drive in UEFI mode
- This should create all the system partitions (recovery, EFI, etc.) on the new drive
- Clone your old main partition by overwriting only the main partition on the new drive (and keep the system partitions)

Does anyone use a Samsung SSD 970 PRO/EVO with NVMe v1.3 on modded motherboard ?

Bonus...
