How To Install Windows On A PCIe SSD

Curiosity got the better of me.

I got a NVME as it was only a bit more than a SATA so tried it.

I didnt need to enable UEFI oprom, I only needed to make sure its booted in UEFI mode, and UEFI mode doesnt require UEFI oprom to be forced. So I can still use MBR usb sticks.

So the only requirement is that any OS that needs to access the m.2 NVME device has to be booted in UEFI mode. It doesnt require "uefi only" oprom.

With microsoft's nvme driver apparently broken (No FUA support?) I couldnt get a working nvme RST driver because intel seemingly have abandoned win 8.1 completely. So I am using samsung's nvme driver.

It bench's extremely fast but real speed is currently slower, slower boot, slower shutdown, slower system tray load up after login.

Hi there,

I was reading through the Original Post about installing the Nvme driver provided by the manufacturer. I was wondering how can we install the Nvme driver before installing windows 10 on M.2 PCIe ? Thank you

I installed win10 successfully on my PCIe SSD. I didn;'t have to turn CSM off, it detected the drive immediately with the full name in UEFI.

The only thing I had to do is to flash the Bios version 2.90P from ASrock website and that's it.

I can't get my computer to boot from PCI M.2 SSD:

OS:            Windows 10
Mainboard:     AsRock H67M-GE
UEFI Version: P2.10
SSD:           Corsair Force Series MP510 NVMe PCIe Gen3 x4 M.2 SSD (240GB)
Adapter:       PCIE to M.2 Adapter (EZDIY-FAB M2 20190424)

The M.2 SSD is mounted on the adapter and the adapter is in the PCI Express 2.0 x16 slot.
Running Windows 10 Installation CD, it identifies the M.2 SSD and I'm able to install windows on it. The Bios though does not recognize the M.2 SSD as a boot device. In fact it does not recongnize it at all. When I boot from the standard HDD, Windows recognizes the M.2 SSD and I can use it as a hard drive.
The sequential read/write speed is about 1500MB/s / 1000MB/s so just 50% slower than its max speed.

Uploaded the latest BIOS version (from 2012 !?) and tried all relevant settings. Nothing works.
The CSM (Compatibility Support Module.) option/button -as mentioned above- is not in the UEFI setup utility.

Am I missing something or is this board simply not capable of booting from a PCI M.2 SSD?
If so, why can Windows use it as a hard drive?

Thanks in advance for inputs.
