I am using an Asus P8Z68-M Pro motherboard and a PS/2 Keyboard. My keyboard does not work in boot menus like when I'm selecting an OS and when selecting which kind of Windows safe mode to use. The keyboard works fine at all other times without any problem. The keyboard even works in the ASUS UEFI BIOS Utility.
Can anybody please guide me to what I can do to solve this issue?
Oh, and one more thing: I found this neat little trick to bypass this bug, i.e. to keep hitting any of the arrow keys when the computer loads. Then the keyboard works fine for that particular session. But this is not very practical on a day-to-day basis.
