We ordered and received 4 new OptiPlex 7440 AIO All-in-One computers without Windows installed - only Ubantu is installed. The desktops do not have a built-in optical drive. I get the following error message when I try to install Windows 7: "A required CD\DVD drive device driver is missing.” I tried using an external optical drive and USB boot device to install. I am also plugged into the USB 2.0 ports and not the USB 3.0. I tried many of the suggestions Google has provided me, but none of them are working. I'd appreciate any help.
FYI, I called Dell Support twice about this issue. The first technician hung up on me when he realized he didn't know what to do to help and the second technician said I had to pay $89 for help. When I asked to speak to her supervisor, she hung up on me. Since Dell likes to rudely hang up on their loyal customers, I'm hoping the community will be more helpful.
Hello mate, I have the same problem, can you tell me the necessary drivers that I need to add to the boot file? Thanks,
