Acer aspire m5 series

My laptop locked up so I held the esc key while rebooting and a dialouge window came up saying no device to boot and hit any key to continue but it doesnt do anything.. Also I tried rebooting with the alt/f10 keys and a window saying "no bootable device, hit any key" but it doesnt do anything. ok so I did alt/f12 and it said it was doing repair then screen went black, it shut down, so I hit the power on button and it started up to the sign on screen and thought I was home free but now my cursor is flashing in the sign on window but my keyboard is not working. Any help would be appreciated
thank you
