This is the thread about how to flash a modded BIOS, but until now we don’t even know, whether you had modified the BIOS correctly.
Where does it not see your NVMe drive? Is it within the BIOS (as bootable drive) or within the Device Manager of your currently running Windows OS?
To let us being able to check the quality of your BIOS modification it would be a good idea to give us a link to a package, which contains the original and your modded BIOS.
In this folder is the latest BIOS: M5A97-LE-R20-ASUS-2701.CAP
The body of this BIOS file: Capsule_Aptio_signed_AMI_Aptio_capsule_body.rom
The NVMe module that I added to the body of the BIOS: NvmExpressDxe_5.ffs
And the saved .rom file with the added NVMe module: M5A97-LE-R20-ASUS-2701.rom
I purchased a WD BlackSN7100 NVMe SSD with a Sabrent NVMe M.2 SSD to PCIe adaptor.
I plug it into my PCIe X16 slot. Started up my computer. The windows disk manager found it and I formatted it. I then proceeded to try and install my windows 10 on it. I installed it. Rebooted my computer. But the BIOS did not see the NVMe as a boot source. I did research, were I found out that my older mother boards does not have the proper module for NVMe on my PCIe slot. Started looking for resource to see if the BIOS could be modified. Which lead me to this forum. I read over all the information in this forum to modify a BIOS. Download the tools to achieve this. I have the Clover bootloader on a USB. And I am able to run windows from it. But I would rather have the BIOS do it. I hope this detail message help who ever can help me achieve this goal.
Read ALL the details…NOT a summarize reading, specially point#4 of it.
And Windows OS is installed from a clean environment as a system with no OS present.
Secondary old disks should be disconnected until setup completed.

Since this discussion has not much to do with the topic of >this< thread, I have moved it into a separate thread.

According to what I have seen by a short view, you seem to have inserted the NVMe module correctly.
Nevertheless we do not know until now the following:
Has the modded BIOS been properly flashed? Please look into the “Step 3” chapter of >this< Guide. There is a chapter Verification of the successful BIOS Modding/Flashing.
Why didn’t you follow the advices given within the “Step 4” chapter of >this< Guide?
Not wasting more time with this as it seems the .ROM has the NVMe DXE on it, set the bios to UEFI mode (CSM Disable) prepare the USB OS install disk and procede to Windows setup, no other disks connected to the system, later on can be added again.
If no destination drive is visible on setup, then the mod is wrong or not flashed correctly.
Look in the forum how other users with same mb model, had finish this operation…
The forum has a “search box”…
A full UEFI system MUST have in your case (Mb model) also a UEFI GPU, almost sure that that’s the cause of it. So what’s your display card model?
NVMe requires a UEFI environment, such as a modern 64bits OS, GPT file system disk and compatible EFI hardware device initialization, Secure boot Enable or Disable.
So, what I am hearing is that it is my Video card that is stopping the NVMe from working right. And if I upgrade my video card to one of these models. It will make the NVMe bootable?
Your not “hearing” nothing sir…you read my words and believe them or not.
The old card didn’t stop nothing at all because you didn’t yet made any UEFI OS installation…
What i just told before is that the current GPU on the system doesnt met the requirements to set your system in UEFI mode, so if the system can’t be set in UEFI mode how can you expect to set a NVMe disk booting your machine, understood now…SIR???
I checked your .ROM file, the NVME DXE was inserted…was it flashed correctly and now on the system, well i’m not the one with the motherboard next to me am i?
That’s all, good luck.

As you can read within >this< Guide, you will never see your NVMe SSD as bootable device within the BIOS of your old mainboard, but nevertheless you should be able to get Win10/11 installed onto it, if you follow my advices layed down within the “Step 4” chapter of my guide.
Good luck!
By the way:
After having enabled the “CSM Mode” within the BIOS, a device named “PATA” or “PATA_SS” should be listed within the BIOS as bootable device. This will be the proof, that the NVMe module has been inserted successfully, but nevertheless the booting will not work this way (as mentioned within my Guide).
Not the best PCIe NVMe adapter bought by ttis user…but it works, use the PCIe x16(x4) black slot on your mb, what is the model of the NVMe disk you have?
