Hello,
- May I please confirm whether the DVD/CD drive is built into your laptop/PC or if you are using an external USB CD/DVD drive?
- Also, is the disc itself not working, or is the DVD/CD drive not appearing in File Explorer?
Meanwhile,
- Open Device Manager.
- Expand the arrow next to DVD/CD-ROM Drives.
- If you see the DVD/CD drive underneath, right-click the driver, select Uninstall device, select the 'Attempt to delete the driver software for this device' checkbox, and then click Uninstall.
- Once uninstalled, restart your computer.
Then, check whether the DVC/CD drive is working.
Let me know if you still need more help.
