Problems enabling Secure Boot

I'm having problem enabling Secure Boot on my home built desktop computer, mother board is an MSI B450M-A Pro, I've followed a couple of videos on youtube and seem to be doing everything correctly and in the right order but in UEFI mode the computer will only boot in to BIOS, if I change back to CSM it boots in to Windows, what I have noticed is that when I select UEFI a drive seems to vanish from the boot priority diagram, Any clues?

    Just an idea but have you got an EFI partition on your boot drive?

    No it would appear not.

    You need to convert your hard disk from MBR to GPT to use UEFI. 

    There are ways to do this but to be honest a clean install would be preferable then you can take full advantage of secure boot.

    The Windows installation on your drive will be for BIOS/legacy boot, and won't start in UEFI mode.

    The simplest solution is a reinstall. It may be possible to convert an install from BIOS to UEFI but I've not tried it. For Windows, UEFI boot requires both a different disk format (GPT rather than MBR) and an additional EFI partition.
