How to set 2 ssd in bios msi?

Question

MSI

Good afternoon, all the disks work in my BIOS. bcl sata ssd, I installed m2 nvme yesterday. The problem is that only one of them is displayed. I found some setting, 2 of my ssds were shown there (this was something like boot priority, but only for ssds, because only they were displayed). I clicked, and a second one appeared in place of the first one (the Linux bootloader from one disk changed to the Windows bootloader). Such question: how it is possible to expose 2 disks at once? And then you have to climb into the settings. By the way, due to the fact that the Windows bootloader is disabled, it cannot even be switched from the Linux bootloader. All disks from under the system are visible.

Answer 1

I'll try to assume that some sata port is conflicting with the m2 slot. On my m / b from asus it is written in plain text that if m2 is connected, then some sata port (like the 6th one) will not work.
So just try moving your sata ssd to a different port.
