Yes, clean install is usually required, there is ways around that but I do not know them or how involved that is. You may be able to backup your current install, mirror the drive, install a new OS, then copy back onto that all the OS folders and leave the new bootloader/EFI partitions in place, only copying over the actual OS install folders and all those contents.
Otherwise, yes, it may be best to wait until your next clean install, or do some heavy research into how to transfer a pre-installed UEFI OS to a new drive (direct exact clone may work, but I'm not sure, especially since new target would require NVME driver loading)

amigo quiero decirle que todo salio perfecto, tenia mucho temor, de verdad, pero confié en usted, y me funciono la bios y estoy trabajando con nvme samsung 960 evo 250gb perfecto!. muchas gracias. me sentí impulsado a donar, no fue mucho, pero de seguro de poco en poco... muchas pero muchas gracias....

@Lost_N_BIOS, thank a lot for the updated bios it saved me quite some money for the whole PC upgrade.
Already send a donation to the forum :)

@ptcz - You're welcome! And thank you for the donation to the forums, it will help keep the site up and running, so we all appreciate that

I'm hoping this thread is still alive!

I just purchased a x79 GD645 (8D), the first time I've got an enthusiast board!! Built the system and flashed this bios on Bios (A) via m-flash... i didn't rename and also flashed the ME firmware as well. So now bios A loops with no post codes, it like cycles on and off every 1-3 secs, and bios B loops with no bios screen but it always stops at 60 then restarts... no output on screen, no usb devices lighting up or anything... please help!

N.B I know I'm silly but I was so excited I didn't think -_- I'm not sure if it's the ME update thats done it or something else? I'm willing to replace bios or something if that would help? Also, I'm on a 3930K so if bios B was V1, thats not whats causing the post fail... any insight would be welcome!

@zenos2008 - What exact board do you have, and what BIOS did you flash in, what post #?? Only BIOS at post #4 is for the GD65 8D board.
Why did you not rename it as mentioned? This may not matter, unless M-Flash tells you no BIOS found, but if it finds it and flashes it then I guess renaming it's not required on this board.

For booting to the other BIOS, try clear CMOS and boot it again with one stick of memory (make sure it's in correct slots per the manual)

Some 3930K (C2) may require 1.4 BIOS, so if backup chip is 1.0 and you have C2 CPU, then it's not going to work and you may need to pickup some cheap chip mentioned at post 20-23 that's compatible with 1.0 BIOS (NOT 3820)
For that, you'd need to ask MSI directly, since it appears from their list that ONLY C1 3930K is compatible with BIOS 1.0

Or get flash programmer so you can then directly update both BIOS to latest again

OK, that sounds promising. I'll check the stepping of the cpu, thanks. And on why i didn't do those things? I'd downloaded (the correct) bios a while ago and was operating from memory. I've flashed a nvme modded biod on my old z68 asus board a while ago and thought nothing of it. As long as itcan be re-programmed at the end of the daym that's a relief. I'll keep yopu posted. Thanks a lot for the advice

Yes, you can always fix with programmer, once you have one. You still did not say, what exact board model you have, there is a few MSI X79 variants and it can be confusing, best to check the sticker on the board to be sure.

Oh sorry, X79-GD65 8D (MSI-7760 v1.1). I was worried about the ME firmware update screwing something that couldn't be undone. I was coming from 4.4 on bios a i think.... I've never checked Bios b so im just hoping the bootloop is cus it's my 3930k isn't supported as you're correct, it is C2 stepping I've got. I'll order a cheap xeon that's compat with v1.0 see what's what!

@lost_n_bios hi
i have also msi x79a-gd65 8d with 4930k
i am using my nvme sandisk ssd with adaptor for couple of months
I want to use it as primary drive
it seems that bios version is 4.8
If you guide me about bios update with your modded nvme boot support it will be wonderful and i will be happy about to donate for that.

Very Thanks

I understand how it concerns you, give me a few minutes and I will edit in modified BIOS to this reply
Which board exactly X79-GD45 or X79-GD65, your title on the thread is a bit off
This one, GD65 (8D)? It is only one with BIOS 4.8

@stevedri - Here is NVME Mod BIOS for the above linked board

I made this one again ... based on MSI Bios v.4.8 X79-GD65 , but i am not responsable for eventually brick,
you can check the bios and NVME module into, before flashing it.

Here is the Guide :

[HowTo] Get full NVMe support for all Systems with an AMI UEFI BIOS

It's better to buy and SPI Programmer CH341A + Pomona Clinp to be sure to recovery your system !
Here you go :

P.S. this mod is made by UEFI Tool 038 and NVME module NvmExpressDxe_4.ffs.

Let me know

This is the original bios file X79A-GD65 (8D) (MS-7760) Latest Bios 4.8 :

Thanks for your kind help

I have multi bios and i should update Bios B with 3820 cpu to bios 4.8 version
I am looking from friends and second hand for that update
After that i will apply your modded bios
With that even there will be brick i may work with other bios i think


Important Question: Is it GD45 or GD65
I have gd65 and its latest bios from msi is 4.8
On the other side very similar name GD45 latest bios from msi is 12.8
