Windows 7 Installation, Missing CD/DVD Driver

Solved/Closed
Hello,
I downloaded the Windows 7 RC yesterday afternoon, I am currently on Vista and I have no issues with my drivers, my device manager is perfectly normal. I burned the ISO I downloaded, booted from it on my PC, followed the prompts and then encountered the following error message:
"A CD/DVD drive driver is missing. If you have a floppy disk, XD, DVD, or Flash USB drive containing the driver, please insert it now.
The problem is that I don’t understand why it can’t find this driver, here is an image when I check the details of my CD/DVD drive:

I really don’t understand this error because the drive works perfectly, as the installation of Windows uses this same drive.
Thank you for your attention =D.Configuration: Windows Vista Internet Explorer 7.0

  1. Hello,

    I had the same problem, but I managed to solve it. The solution is below.

    I have a newly acquired SSD (OCZ Agility 3 SATA III 2.5'' SSD), and I'm installing Windows 7 from a USB drive. During the installation, I got this message:

    “No device drivers were found. Make sure that the installation media contains the correct drivers and then click OK.”

    My installation is in English. I initially thought it might be related to the Windows 7 installation, so I downloaded another version (in French). However, that wasn't it, as I then received the same error message in French:

    “A CD/DVD driver is missing. If you have a floppy disk, XD, DVD, or USB flash drive containing the driver, insert it now.”

    I then tried to install Windows 7 from a DVD drive, but that didn’t help either. I tried copying the RAID drivers from my motherboard onto a second USB drive, but the Windows installation did not detect this second USB drive. I tried switching to IDE mode instead of AHCI. Nothing worked. I attempted several DISKPART commands, but it didn't change anything.

    The solution that worked:

    Finally, I simply combined two solutions (I don't know which one was crucial): I removed the USB drive containing the Windows 7 installation from its USB 3.0 port and plugged it into a USB 2.0 port. Then, I disconnected the SSD from the SATA III port and connected it to a SATA II port during the installation. It worked; I was able to install Windows 7, and once it was done, I reconnected the SSD to SATA III.

    Given how much I struggled, I’m posting my solution here, and maybe it will help others.

    See you!
    1. Indeed, simply moving my USB stick from a USB3 port to a USB2 port resolved the error message. It just takes longer to install...
      My internal hard drive has always remained connected via SATA III.
    2. Hello,

      that's right! After two hours of searching for a solution on various forums, I saw your message and bingo! I plugged the bootable USB drive into a USB 2 port and it worked!!

      Thanks for the information.
    3. Same for me, I was trying to install Windows from a bootable USB flash drive but I kept getting that message about the missing CD/DVD driver (even though I don't even have an optical drive).
      After struggling for a while, I simply changed the USB port to connect it to a front port on my tower, and it worked, no more silly message.

      Good luck!
    4. Same! usb3->usb2 and it works!
    5. Great! Thank you very much :)
