Hello, I would like to install CentOS 7.3 on my new Lenovo M900 machine. I am using the official 1 DVD installer. The installation process was fine without any error but after reboot the USB keyboard and the USB mouse did not work. Therefore I was not able to type anything or pass the first boot screen. Only the power button is working. Any idea why? I believe the installation media is using the same kernel components as the installed machine. So why the installer is working and the installed system is not? BR, Zsolt
