M.2 NVME drive with PCIe adapter as a boot drive

[BigBakwas]

I upgraded to a Samsung SSD by cloning original boot drive. It works fine. Now I installed a Toshiba MVM M.2 SSD through a PCIe adapter card installed in a X4 PCIe slot. I was able to clone the boot drive (Original SATA SSD) to the new M.2 drive. Windows is able to recognize this drive and appears in file explorer. But when I want to make this new M.2 drive as my boot drive, it does not appear in BIOS and booting fails when I have the original SATA SSD disconnected. What do I have to do to make this work? Or the motherboard cannot accept a M.2 drive? Attached is the MoBo picture (from Google).

To be able to boot from Windows installed on NVMe drive, several things must be true:

1) PC must be in UEFI mode

2) Drive must be formatted using GPT, not MBR

3) PC must support native booting from NVMe drive

I suspect the latter is not true with your PC because if it was, there would be an m.s NVMe slot in your motherboard -- and I don't see one in the picture.  Windows 10 has native NVMe drivers, so you can use the drive, but you can't boot from it.
