Hi Jcwisgod,
Thank you for your response.
.
Secure boot does not load the USB drivers, so if you boot to the bios and the keyboard is USB, you would not have a input device recognized. It has to do with the way the bios is setup. .As you have now been able to select secure boot, would you be kind enough to mark this as solved, so other people will find it easier to find. Thanks in advance.
