@Fernando I have not tried to install a fresh copy because of this:

Microsoft describes the Windows 10 free upgrade as a full version, not a trial. Contrary to these statements, Windows 10 free upgrade does have some restrictions.
If you upgraded from a retail copy of Windows 7, Windows 8 or 8.1, the Windows 10 license carries the retail rights from which it was derived – can be transferred. But under Microsoft’s rules, you are only entitled to a one time transfer.

If I am wrong, please inform me. I would like to use that one transfer for a build I will do when Ice Lake releases.

So Fernando, I have another question for you. Im still waiting for my new adapter card to come in, but I noticed somthing while looking mat the other one I have lying around.

See those two spots on the pins, where there are only half pins instead of fully connecting to the bottom? What affect do those two half pins have on the functionality of an adapter card? Would that cause it to not be detectable as a boot device?

Here is a picture of the other card I ordered (the one ive used in the past multiple times with success)

Notice it has a full pinout into the expansion slot.

Hi Fernando, help me out if you can!
I have hp z620 bio 3.91 version and nvme samsung 960 evo 256gb. I was able to boot to windows 10 but need usb clover boot loader attached to the pc in order to boot from ssd. I followed your guide to mod bios with Nvme efi file and I did flash the rom but the bios still won't see ssd drive , nor boot from there. can you give me direction. if any information needed let me know.
tom

here it is . I am not sure that will give you what you need to see.

@Fernando:
I took your advice and re-installed Win10Pro. I retained the license because it was linked to my MS account. However, the Sequential Read-Write speeds on Samsung magician went only up to 2284MB/s and 1657MB/s respectively. Now the drive hardly has 100GB in it. I also made sure to install the samsung driver and do the "performance optimization" in magician. The speed challenge continues for me.

Hi everybody!!!!
so Two months ago I tried modding my bios....with total .....UTTER....FAILURE!!!!

I've got a awesome MSI x79 big bang power II motherboard...with no NVME support!!!
I followed the info on this post made by @fernando.
It was brilliantly laid out...easy to follow...but every time I tried loading the modded file I was rudely told that there is no supported Bios file to upload!!!
the long and short is that I just loaded a clean unmodded BIOS file.....Made a Backup of that file.....modded the backup file (without changing its name)...loaded the modded backup....AND IT WORKS!!!!!

I have Full functionality of all features....The nvme shows under boot devices....I dont have to switch any functions off...IT WORKS GREAT!!!!
Two months down the line and its still rocking!!!!
I now have a 3 second boot time!!!!
Its amazing!!!!

I've Attached the modded bios file...It works for me ...but like any modded bios file ...MAKE BACKUPS!!!

Thanks To all!!!
pics and file attached ...
I take no responsibility if you use this file ...PLEASE TEST FIRST....but like I said ....MINE WORKS GREAT!!!!!

I've followed @Fernando s guide a year almost ago and managed to get it working on my Gigabyte X79 UP4.

Fasttrack to today, my game freezes, I force restart it (windows updates were pending as well) . Upon boot I see that the NVME driver is gone from the device manager and that I'm running on my backup old drive.

Any idea what happened and how to go about debugging this ? :|

Thanks

here is zip file format. I appreciate you looking into it.
