Error: "Still waiting for root device"

My monitor is connected with HDMI

This is like pulling teeth, connected to what ?

To my GPU of course.

To my GPU of course.

Why "of course" ?
It could be the integrated graphics or the graphics card.
Many people with Nvidia cards that rely on the web drivers to function install the OS using the integrated graphics.

Oh, ok. Sorry. Now I entered the setup but the funny thing is that I can't move my mouse or type something.

Hi both.

This will probably be of no use but the two black ports underneath the PS/2 port on the back-panel are the ones that the motherboard keeps live for BIOS work and don't need an OS to activate.

The fly in the ointment is how MSI have arranged their ports. They use an add-on ASMedia 3142 chip to provide USB3.1 ports AND an ASMedia 1074 Hub. There is a good chance none of these will work until macOS is fully loaded. You should only use the Intel ports for set-up. (3x USB2 and 1x USB3 on the back-panel are Intel).

Thank you for your response.

So I tried every port back and front but nothing seems to work, not even the PS/2 ones. The only working one is underneath the ethernet cable that the USB for the installation is plugged in.

I actually fixed the mouse using the USB Type C with a USB converter. I installed MacOS on my disk but now when I try to boot from the disk so it finishes with the installation (create users, etc.) I'm stuck at this point.
