New build doesn't detect Samsung m.2 nvme

[Garyj881]

Purchased the following
9800X3D
MSI MPG B850 Edge Ti WiFi
Patriot Viper Venom EXPO 32GB DDR5 C30 6000MHz

I have built a new pc today with the above components.

My current PSU is a super flower 750W. I have a NZXT in order, arriving next week.

I have two HDDs installed. A Samsung Evo 980 and WD SSD.

Bios wont detect the m.2 drive so cannot install windows. I have tried it in all 4 m.2 slots and updated to the latest bios. Still won't detect my Samsung m.2 drive.

Any help appreciated.

Is this a new empty drive, or an existing drive?

If an existing drive, does enabling CSM and/or disabling secure boot help? If the drive previously had Windows installed, it might be formatted to MBR and new boards expect you to use GPT.

This is a drive pulled from my old pc. It has W11 Installed.I have tried enabling csm and disabling SB. No difference.
