I unplugged it immediately afterwards, my PC locks up if i have a flash drive plugged in at start up.
I'm stumped. Also if you reinstall Windows on your PC does it format your Hard Drive and delete all your stuff?

ya, but there should be a repair mode for the installer... i think its f9 during installers boot or something
