When you turn on your Lenovo computer, hit F11 real quick, it will take you into your bios. F1 and F10 take you into a bios, too, but you can’t do anything in there so I use F11. Once you are in your bios, just tell it to boot from your USB drive.
The other thing you need to do is connect your computer to a CAT 5 or Cat 6 cable. Once you connect, go to wireless networking, find your router on there, give it the password and connect. After that, disconnect your cat 5 or cat 6 cable. You should be connected, now. [br]
