I have a strange issue haunting me. On a dual boot PC (Windows 7 x86 and x64 the OS selection (Windows Boot Manager) will not allow me to select with the arrow keys. Also the enter key will not allow bypassing the timer. I recently reinstalled both OS but it never worked previously when I had Windows 7 x86 and XP x64 on a dual boot.
During the install, during the several restarts that occur when you are doing an install it will work and I could select but now I cant. The keyboard is a USB keyboard with wireless mouse.
