I first rewrote the thumb drive on another computer here at work. Then, at a home computer, I downloaded the iso file to my desktop (220M). Last, I ran the third program. I designated the iso file on my desktop at home and pointed the program's output to the thumb drive. Then today I hit F2 on the infected computer, with the thumb drive inserted, and let the computer boot up. I tried rebooting several times, and while the thumb drive light flashes a little, nothing else happens. I don't have a camera here at the store but could bring one tomorrow. Any other thoughts so I can try and make it work more quickly?
