Im having the same problem when trying to upgrade to windows 7 ultimate, its not allowing me to go past selecting the language because the "drive device driver
is missing" (or something very much along those lines is the error)
I have an Optiarc dvd rw - (s3), and when i look for the driver on the official site there isnt one....but the device works fine on the current installation of vista.
anyone got any suggestions?
would be very much appreciated,
