How to set M.2 NVME drive to boot on Asus B85M-E?

[UberTiger]

I managed to install windows to the drive using a bootable USB, but I can't seem to see in the BIOS where I can specify that it boots from the new m.2 drive.

I'm using this PCI-Express Asus Hyper m.2 adapter card along with a Samsung 960 Pro M.2 drive.

This is the motherboard

I updated the board bios to the latest version, 3507, but I'm not sure what else I need to do.

Many thanks

If I boot into the old hard drive, the new M.2 does appear in This PC with the clean windows install files on it.

can you not select "Windows Boot Manager" in the menu rather that the drive?
