Hi,
Welcome to Microsoft Community and we are happy to help you on this issue.
As per the query description, it seems like you get an error message prompting “No CD/DVD-ROM drive found” when you try to start a program after installing it using a CD through an external CD/DVD drive.
I would like to gather some information on this issue to help you better:
- Is this issue specific to particular program on the computer? If yes, what is the specific program that you are trying to start?
- Are you able to use other CDs or DVDs on CD the internal drive on the computer?
- Does the program requires a disk to run on the computer?
If it does not require a disk to run the program, I would suggest you to copy the files on the hard drive and then use the files to run the program.
As we are unsure about the exact reason that has caused this issue, it would be better if we can get more information on this issue.
Please reply us with more information on this issue to help you better.
