Ok so im wanting to sell my computer so i decided to factory reset it so i go into the settings and click the restore button i did everything it told me to do. Everything was going fine until it hit 66% it then sat there for about 10 minuets and said that the reset failed. So i clicked cancel and it brought me to a menu where i clicked to retry it. And the same thing happened again. So i click cancel and then just clicked to restart the pc so that i could try to do it again from the start but its not letting me it gets to a boot up page and says "An operating system wasn't found." i understand what that is telling me but My mouse and key board are not working for it either so its just stuck at that screen and have no clue what to do because without the keyboard i cant enter the security reset screen.
