In today's article, excluding cases of hardware failure, TipsMake will guide you on how to fix the Windows 7 error of not recognizing the CD/DVD drive with just a few simple steps on your computer.
To ensure the absolute security of information stored on your computer, Windows 7 has integrated several security features, including a feature that helps identify whether drivers are from trusted sources.
In this case, the problem may be that the driver for your drive is not considered trusted by Windows 7, so it won't recognize it.
To fix the Windows 7 error of not recognizing the CD/DVD drive:
Step 1 : Turn off and restart your computer, press the F8 key on your keyboard to access the Advanced Boot Options window in Windows 7, and select " Disable driver signature enforcement" .

Look at the right-hand column, click on the UpperFilters and LowerFilters items , right-click on those lines and select Delete.
And this is the result after deleting those two items.
After deleting the drive , restart your computer to see if it recognizes the drive.
If it still doesn't work, proceed to step 3.
Step 3 : Open the Command Prompt window (refer to the article "6 ways to start Command Prompt on Windows 7 ").
