Hi.. i have sony vaio laptop with windows 7 home edition now i want to install windows 7 pro in my laptop..

i have the ISO of win pro, because my CD drive not working i m trying to install from the USB .. windows setup started but it shows error when i click "Install Now"


"No device drivers were found. Make sure that the installation media contains the correct drivers, and then click ok"

That message gives me 3 buttons: ok, cancel and browse, neither of OK and CANCEL would let me through the install, and with browse.
