Easily Fix a USB Keyboard that isn?t Working Properly

If you have a USB keyboard or mouse you may find that it doesn’t work correctly, or it isn’t usable while Windows is booting up. This can be a major problem if you need to access the Windows Advanced Options menu, but your [F8] key isn’t working. If this is the case you need to enable USB legacy support, as follows:
1. Enter your BIOS settings by pressing the correct key for your type of BIOS (usually [F1], [F2] or [Delete]).
2. Look for the USB Legacy Support setting. It will usually be in either the Advanced, Peripheral, or Peripheral Configuration menu.
3. Change USB Legacy Support to Enable, save the changes and exit by pressing [F10].
