I am trying to install windows 7 Ultimate 64 bit on a new system and it starts the install, but stops with a message that a required CD/DVD drive device driver is missing. System has a LG SATA cd/dvr, so I checked LG's site, found that there is an update that adds win 7 capability. I have no other system to flash the drive in, so I called LG. They said no drivers are needed, that my install disk is bad. I downloaded the img file from Microsoft, and have burned it w/ 3 different burners/software, still the same message?! I also installed a lite on ide burner, did install, same message. Help!
