Question Samsung 990 pro (2TB PCIe 4.0 NVMe M.2 SSD)

[ThatGuyFox]

I have recently purchased a 990 pro M.2 for some extra storage with fast ability to read/write files. Upon installing in my computer, I get brought to my BIOS in which upon looking, my boot device is not selected to boot from. Its actually not even listed as a boot device. Only thing that pops up would be my Seagate 3TB HDD which my boot settings is on a 1 TB SSD. But pulling that 990 pro off of my computer, all my other storage devices work as normal and my pc boots normally. However, when in my BIOS, there's a setting option for my storage devices that allows me to see my storage devices. The 990 pro is a PCIe 4.0 which i know for certain my motherboard supports PCIe 4.0 M.2's. If anybody has any clue as to what is going on and can help me out, that would be much appreciated as I am mind blown as to what is going on.

PC SPECS: (Will list more if needed. Figured this would be specific enough)
Motherboard - ASUS B550-F Gaming (Wifi)
Processor - Ryzen 7 3800X

It can't be seen as a boot device, unless and until there is an OS installed on it.

As far as other drives not appearing, very often, installing a PCIe drive will disable one or more SATA ports.
The "fix" may be as simple as moving your SATA drive data connections to different ports.

My guess would be that you installed the 990 in a port that automatically disables whatever port your boot drive is connected to. That's fairly common.

Solution would be to connect the disabled drive to some other port.

Look for info on that in your motherboard manual.
