Hi, just joined. I'm trying to update an older machine to NVME boot utilizing an extra Samsung 960 evo M.2 via a PCI express adaptor. It works fine for storage with awesome read/write speeds but although I can install windows it will not boot.
I am currently running Gigabytes U1j beta BIOS for UEFI support. BIOS ID 8A11AG0B, it's dated 03/06/2013.
I even cloned a SATA install, that worked great at first, but only booted a few times (Possibly just once...) and failed, not sure why.
Any help given would be greatly appreciated, you are doing an awesome thing here!
Thanks to all!

You need mod BIOS to boot from NVME, that is why your attempts are failing, and you can't clone previous OS from SSD to NVME without doing things in a certain way (must be converted to GPT initilized disk etc)

Here's a few ways to clone if you wanted, but I do suggest a clean install
Installing Clean Win7x64 on M2.2280 PCIe Gen3x4 SSD A-DATA SX8200 Pro << My way, will work for Win7 or Win10 (if cloning Win10- start at step #4, skip #5)
[Guide] How to get full NVMe support for all Systems with an AMI UEFI BIOS (330)
[Guide] How to migrate Windows 7 64bit boot drive from MBR SATA to UEFI NVMe without data lose

Once you install NVME mod BIOS, if not cloning drive and doing clean OS install as suggested, you need to follow at steps at #4 exactly in the "This is what you should do" section of this guide

Thank you!!! Modded BIOS in like a minute and the cloned OS I already had on the NVME drive booted on the very first try!
It's truly awesome when more knowledgeable people freely and kindly share their expertise, thanks again!!!

@ktmaniac - You're welcome And thank you for the quick test and report back!!

Hi Im hoping you could help me I have a somewhat similar board and wanted to mod as well Gigabyte Z68XP-UD3R to support nvme im not able to open up the bios using mmtool how were you able to open the bios file?
