[SOLVED] NVme makes SSD undetected.

[BNestor]

I just got my new NVme ssd (Samsung Evo 970) and installed it.
Problem is that my mobo detects the Samsung Evo but no my old SSD (In BIOS).
As soon as i take it out i can load into windows (Installed on old ssd)

Can some mobos only use one type of storage at a time?
My motherboard is the Aorus B450 m .

the m.2 slot takes bandwidth from one SATA port. I'll bet if you move the SSD to another port and verify the boot order you can use both.
