NVME drive not showing up as boot option, but is detected by the mobo is storage devices

Feixas

Hi guys, I bought some new components (3600, b450 carbon ac, kingston a2000 nvme ssd).

After assembling everything, I went to the bios, and select my usb drive as the boot option (windows media creation tool), and then selected the ssd as the installation device, and it started doing its thing. 

When it finished installing, it kept going into the Windows Setup, so I went to the BIOS, and the SSD is not showing up as a boot option, any ideas why ? 

I have it hooked up to the first m2 slot on the mobo, and I have a hard drive connected via sata as well.

You can try forcing EFI booting and UEFI stuff first on CSM (or switching CSM off altogether), BUT if Windows installer was launched in Legacy mode - that NVMe probably won't be bootable.

I'm sorry, but I'm a freaking noob. 

I don't really know how to force EFI booting and UEFI stuff first on CSM. 

I don't know if the Windows Installer was launched in Legacy Mode, but there's a setting that says something along these lines "Legacy / UEFI" or "UEFI", I don't know if you're referring to this. 

Anyways, I managed to install, and boot from the NVME drive with that setting set to Legacy/UEFI, even though it still doesn't show up in the Boot options as a drive, only as a Windows Boot something, I cant remember the exact name, but it boots.

I tried doing the same thing with it set to UEFI only, but then it keeps booting into the USB drive.

Good. Windows Boot Manager is always what you should see when you do NVMe installation and that is what should be picked from boot options.
No further tweaking needed.
