Give this a try:
The reason for this problem seems to be the NERO burning software. It changes your computer’s settings in “Services” during installation i.e. the IMAPI service is set to “disabled”.
Here is how you can resolve this problem:
- Open your Windows Control Panel and go into Administrative Tools > Services
- Scroll down to “IMAPI CD-Burning COM Service”
- you will see that the item is “disabled”
- double-click the item and reset it from “disabled” to “Automatic”.
To save the changes restart your computer.
That’s it. Your CD-ROM drive will be accessible again!
