Windows 10 install uefi nvme

Hello,

Im currently in the process of installing windows 10 on a samsung pm951 m.2 pcie nvme ssd in uefi mode. The problem i am having is that the windows installer does not see this drive. I have a uefi bootable thumb drive but unless i run in legacy mode the
drive cannot be found. Samsung references the standard MS nvme driver but i can not find it anywhere, they do not provide their own driver for this drive. Any help would be appreciated.

 

UEFI vs Legacy boot mode

Yep, UEFI mode with Win 10 loading I get the Asus logo.

IIRC there maybe an option within motherboard UEFI to disable the Asus logo but not looked into it. On another forum I have read that what logo you get at Win 10 loading is the easiest way to know what bios mode OS is in.

If system is booting in legacy mode - you get Windows Logo.
If system is booting in UEFI mode - you get OEM logo.

Above also applies to Win 8 but not Win 7.

 

Win 7 booting from Samsung 750 Evo sata SSD in pure UEFI mode Class 3 but not from NVME

Hello everyone, Straight to the issue:

I have running windows 7 which includes Microsoft Stornvme KB2990941 and KB3087873 installed, driver working and windows running correctly.

1. Win 7 boots from Samsung 750 Evo sata SSD in pure UEFI mode Class 3 CSM Disabled, Works correctly

2. The Same Win 7 Cloned from the same Samsung 750 Evo sata SSD to NVME Drive which does
not boot in pure UEFI mode Class 3 CSM Disabled but
boot perfectly in CSM mode on (Legecy support on)

3. Why it boots from Samsung sata SSD in pure UEFI but
not from NVME in Pure UEFI mode

4. It's booting in UEFI from Samsung Sata SSD in Pure UEFI that means my
files and partitions are laid correctly.

5. When CSM is disabled and booted from NVME then it gives

efi\microsoft\boot\bcd

0xc000000d Error

Error reading boot data or something like that.

Why it's doing so, I want to boot from NVME, I tried every hack possible to install windows on NVME drive directly, Windows installs but when windows starts in Pure UEFI mode gives the same error but doesn't give error on CSM ON.

Kindly help I am trying every hack even inserted windows 7 files in windows 10 installation

Added Windows 7 wim and renamed to esd extenstion in windows 10 source folder when installing.

It stuck on Windows logo when installing.

Kindly help I am working with this issue from 3 months.
