Can't Access Bios

Mathens

I have a MSI B550 and I recently made a few bios changes, disabling CSM among them. Since then, windows works fine but I cannot access the BIOS. It is the same for Del on boot or if I tell windows to reboot to firmware settings. I just get a black screen. Ctrl Alt Del will restart the computer from there. I tried resetting CMOS by removing the battery. This undid my XMP but the bios still won't show up. I even tried flashing it but the problem is still there. Any ideas?

unplug/remove your boot drive.. this should force it to go into the BIOS.

Tried this, still getting Black Screen. Weird thing is that CTRL ALT DEL restarts to Windows which would imply the bios is running. I have now tried a different monitor and it still shows Black Screen for BIOS.
