I was resetting my Toshiba to factory setting and half way through the electric went out and now there is a message that says No reboot to restart my system. I have tried everything. I got this laptop toshiba C850 satellite through a training program and it came with no reboot disk. I am a mother of 7 can't afford a new laptop or the $40.00 for a reboot disk. How can I reboot to get every thing back to factory setting .
