Question M.2 SSD

[Shinnio]

So im trying to install a Kingston a2000 250gb m.2 ssd on a ROG Strix ZE90-F Gaming motherboard and the m.2 wont show up in the boot menu. It shows up as a ssd when i check the nvme settings but it wont alow me to boot of it. I went through the instalation prosess of windows were it showed up, so it has windows on it. But it will still not let me chose it as a boot device.

When i turn on the CMS option on boot it detects it but it just boots in and says that i need to add a disk with os on itand press enter

Any help would be amazing

did you unplug all other hdd/sdd when you install windows on it?

Please correct the Model# of the motherbd, ZE90-F isn't valid as far as I can tell.
