Hiya I recently set up a new core i7 system I'm using a gigabyte p55-ud2 motherboard. I plugged my usb keyboard and mouse into 2 usb's and attempted to install windows 7 but when it asks me to press any button to boot into it the usb keyboard does not work. I can use it to get into the BIOS. I looked in there but there is no usb keyboard and mouse option like my last mobo, usb conyroller, usb storage controller and legacy usb controller are all set to enabled but no joy. I also tried with legacy off. I can get into the windows 7 dvd with my ps/2 keyboard and they both work but I need them working before the os is loaded because I use grub.
