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 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. This is just a tip for the others whose OSes are corrupt and the keyboard doesn't work. But this is not very practical on a day-to-day basis.

keyboard not working doesn't translate to OS being corrupt, specially at boot menu since there's no OS loaded, yet –  WikiWitz Jan 13 '13 at 12:23
I know. I didn't say it had something to do with the OS. –  Hele Jan 13 '13 at 13:14
If it works in BIOS, fails in low level windows menus, and works again in the actual OS environment, this sounds like a Windows driver problem. Is there something special about the keyboard apart from being PS2? Shot in the dark here, but does it work if you boot with no USB devices connected to the computer? –  terdon Jan 13 '13 at 14:55
Its a modern Logitech Keyboard. I'll try the no-USB thing as soon as possible and let you know. –  Hele Jan 13 '13 at 15:57
When I connect only the keyboard and the mouse, it works like a charm. So what exactly is the problem? –  Hele Jan 14 '13 at 10:50
