Hi,
This most likely happens if you the CD/DVD driver are corrupt or if you don’t have the most recent firmware update for the CD/DVD device.
Try to uninstall and re-install the drivers for the CD/DVD device.
Click on Start>Right click on computer>Manage>Device manager>Expand CD/DVD drive>Right click on the option mentioned below and click on uninstall. Now restart the computer to install CD/DVD drive drivers from Windows driver cache.
Also try to run the fixit tool included in the link below.

Once done with the above go to your computer manufacturer’s website and check if they have released any new firmware updates for the CD/DVD device, download and install them if there are any.
