So lightning hit our neighborhood and our power went out. When I rebooted my computer it went to the screen that asked you to press F1 F2 but on my damaged keyboard some of the keys do not work including f1or f2 I did order a new keyboard but it doesn’t arrive until next week. I was hoping I could just put the usb of my mothers wireless keyboard into my towers USB port then click F1 F2 on her keyboard so I can get off the screen but that did not work. I right now have no computer. Any help would be appreciated.
