Hi Fernando,

Thanks for the incredibly in depth guide / look at this subject!
I've gotten all the way through the guide and successfully flashed my motherboard with a modded BIOS.
However, after installing Windows 10 onto the NVMe SSD, it reboots and sits there endlessly loading.
I've waited hours but it makes no progress. Drive activity and CPU phase led's are very active for first 30-60 seconds, but die down after that.

I'm kind of at a loss right now, I've spent the entire day trying to get this working and I have no idea what to do at this point.
The drive / board in question is a Samsung 960 EVO 500G and an MSI z77a-g45 Gaming board.

If I reboot the machine, it'll load for 30 seconds then pop up with an error message stating that the installation was interrupted and needs to be restarted.
I can Shift + F10 and mess around in an incomplete windows installation, but not really useful other than seeing that the drive is GPT and setup correctly.
I've tried loading in some sort of AHCI controller driver before installing, but that didn't work. Chipset driver on manufacturers website comes in exe form, so can't really load that as a driver.

Any ideas what could be causing this? I'm sure someone else has had this happen in this giant thread, but it's difficult to search through this many pages!
Thanks!

Hi Guys and @Fernando,

@Fernando, thank you so much for this great guide (post #1) and sharing your knowledge so freely. It is really appreciated.

I have a Gigabyte Z97X Gaming 5. Received my Samsung 960 EVO drive. It is connected via picie Startech adapter : https://www.startech.com/HDD/Adapters/pc...dapter~PEX4M2E1
I have carefully read post #1 and followed each step. Pulled the latest bios file from gigabyte for my Z97X gaming 5 here : http://download.gigabyte.us/FileList/BIO...-gaming5_f7.zip
Used the UEFITool to add the NVME module found witch is 29 kb.
I did not had any problems with the space so all is fine. I saved the file as Z97XG5F7.rom
I plan to use Gigabyte Q flash utility.

Before updating the bios I'm hoping that someone can give advice:
1. Validate the entry for nvme module is correct ?
2. Gigabyte's Q flash utility seem to use .F format bios. With the UEFITool the option is to save .ROM. Not sure if this is correct and if gigabyte flash tools will accept it ?
3. Has anyone on this forum done the same with gigabyte Z97X gaming 5 and modded the F7 bios. ?
4. Has anyone on this machine been able to select the boot drive at startup ?
5. Lastly, I need courage and lots of it, not sure if anyone want to share their first time experience or do you JUST JUMP !!!

Your comments,suggestions and experiences with this board be most valuable.
Thank you

Thank you sir,

Will do it a bit later.

Currently I'm having another challenge on the Acer E5-575 bios.

I've already modified all existing UEFI's from ASUS (over 60) - I will share it soon! :D

Hi everyone!! Im really new here, I found this forum after some intensive searches about NVMe advantages and new improvements over HDD devices, but right now really Im like confused about if a M2 SSD drive would work on my pc, and if it worth the money over sata 3 SSD.
Right now I have a ASUS p8p67 Deluxe Rev 3, and I think this old motherboard doesnt support boot form pcie m2 device.
My old HDD is getting pretty slow, and I wanted to add some faster device in order to install windows 10 in there. After seeing those M2 on amazon I though that could be a really good idea but now I think is more like a complicated problem if you dont have really new hardware, so then my questions are:

1-Can I install and boot from a NVMe drive like a Samsung 960evo in my pcie 2.0 port(with adapter), and enjoy all the 3,200 MB/s speeds this device has??
2-I have read in this forum that you need an UEFI bios, I dont know if mine has souch thing, I found the bios type info at asus.com and it says this: (32 Mb Flash ROM , EFI AMI BIOS, PnP, DMI2.0, WfM2.0, SM BIOS 2.5, ACPI 2.0a, Multi-language BIOS, ASUS EZ Flash 2, ASUS CrashFree BIOS 3, also I read about some devices that works with all kind of bios, like samsung 950 pro which has its own controller inside.... so a 950pro, with an adapter, will it work with my mobo?
3-If I make it work... and taking in mind that my mobo only have pcie 2.0, would an NVMe make some big difference over a for example Samsung 850evo Sata 3 540mb/s?

This is an incredible forum has a lot of info about storage devices, drivers and a lot of things, I expended today like 2 hours searching here for some info and reading about this. Good place.
Thanks for your time, and sorry if those are silly questions, but I must buy an ssd and it seems you guys can give me a really good advice

Hi Fernando!!! thanks for your advice really.!!! And yes, Im a programmer and sometimes a casual gamer, I dont know if it will worth, but my passion for hardware and all that kind of stuff tells me that I must try it!!! hahahah
Is there any risk of damaging the mainboard inserting this module? I remember years ago when I updated an old motherboard award bios 775 that I had, from windows asus utility and just got stuck, for hours, I rebooted, and never boot up again. :( now Im like afraid about the same thing with this one. I think that any kind of bios related operation could be risky.
A friend of mine told me that the NVME speeds are more impressive just in paper results, he says that installing this kind of drive in this pc will be more complicated that the benefits that I can get like boot 2 o 3 sec faster into windows or loading some kind of game.
What do you think about Pcie 2.0? will be able to get at least half the speed of the device? 3.200mb/s is imposible, but at least 1.500 mb/s??? and what about the one you mentioned in that comment at the tutorial: ( Some NVMe SSDs like Samsung's 950 Pro SSD are natively bootable in LEGACY mode (CSM and loading of Option ROMs has to be enabled within the BIOS), because their Controller chip contains its own NVMe supporting Option ROM module.) I just thinking about avoid bios modifications hahahah or leave as the last option for now

I was trying your tutorial anyways, in order to see its complexity... im getting : (reconstructVolume: root volume can't be grown) when I tried to save the modded bios at the UEFITool
here goes an ScreenShot: https://ibb.co/cixY2k Im doing something wrong? has this files some kind of certification, or validation? , I mean if that thing is signed and could it fail because the signature is invalid due to manipulation

Thanks a lot Fernando, Im at the office right now, don't have here my pc, I will try tonight to flash with the modded bios, if boots up, I will buy the 960 evo. is pretty cheap for its performance.
Can I upload and show you my modded bios before upgrade? in order to make sure that I didn't screw something more!! haha I very appreciate your help, thanks really.

Yeah!! Ok, I made those changes to the original file, It seems now I have the NvmExpressDxE module at the bottom of the DXE drivers section, but inside that there is another sub section called "Compressed section" is that good?? I uploaded the file just here :

If you want to give it a look and tell me
