Question boot after new NvMe not possible

[n0rthV]

Hello there,

I need some help with a NvMe and ssd.

Following system:
amd ryzen 7 2700x
gigabyte radeon rx 5600 xt
asus rog strix b550-f gaming
1 TB HDD
250GB SSD SanDisk external
1x 3.0 NvMe 980 Samsung 1TB
1x 4.0 NvMe Kingston KC3000 7000mb/s 500GB

So I ordered the kingston Nvme to migrate my system to an Nvme from my external ssd.
following problem:
I installed the kingston to the 2nd m.2 slot, following that my system just didn’t want to boot.
I took it out, same thing happened.
Then I started to plug all storage media out.
When only the ssd was connected it showed up in bios.
Then I plugged in the HDD, it showed up too.
I plugged in the 3.0 nvme into the upper spot (where the kingston was when the system didn’t boot). It showed up in the bios.
After that i plugged in the 4.0 and the ssd suddenly didn’t show up anymore.
Now I‘m done trying for today, I‘ll keep going tomorrow.

Does anyone know what I should do next, or even better what the problem is?

thank you in advance

Return the system back to original configuration.
Does it boot up?

when i remove the nvme from the upper slot (probably socket 3) it boots up

when i remove the nvme from the upper slot (probably socket 3) it boots up

so does that mean i cannot use ANY Sata slot if u use both nvme‘s?
but i can see the HDD when i put in both nvme

Then your current drive(s) are in a port that is disabled by use of the M.2 drive.

Move it or them to other SATA ports.

No.

It means you cannot use the SATA 5 and 6 ports.
