I just booted my computer through BIOS to load Windows 7 on my SSD. When it got to the log in screen, my keyboard and mouse wouldn't work. I tried unplugging and different ports, neither solution worked. I also tried rebooting several times and still nothing. I am currently running an earlier backup through my external HDD and everything works with no problem.
I should also note that before this happened I was about to install Windows 8.1 to dual boot with 7. I had downloaded Windows 8.1 onto a USB that I then booted from BIOS in order to install it. During the process of installing, I accidentally closed out of the installation and restarted my PC. That was when I booted Windows 7 from my SSD. I am thinking that during the installation, I must have messed something up perhaps drivers wise that effected my USB devices when I tried to reboot again. I just don't know what it could be, any advice? Or possible solutions?
