I have a gigabyte motherboard.
When I boot the computer, I can't access the gigabyte boot screen and the keyboard is unresponsive.
Later, when Windows 11 starts, the keyboard and mouse are connected.
But my Logitech keyboard doesn't work at the moment, only the mouse works.
I have uninstalled/installed Logitech software several times, but the keyboard only works when Windows 11 comes in.
Check your keyboard connections and try a different USB port. Restart your PC and press the boot screen key (Del, F2, or F12). If the keyboard still doesn’t work, try using a different one.
