Burning CD R

I am a novice trying for thr first time to burn a backup disc for some of my files using Nero Express. I get a message indicate the burn is complete. However when I insert the CD in my C drive to check it, and go to run I get a message "insert disc". I start over and reinsert the disc with the same result. Do I have a hardware, software, bad disc, or is it just plain ignorance of what I am trying to do? Any help or suggestions would be welcomed. Thanks a bunch.

 

What are you trying to burn to the cd-r?

 

I'm trying to burn a backup for the (text) documents I have on file

 

Is it like this with other discs?

 

Yes, I've tried two other new discs. I also get the "insert disc" message any time I insert a new unused disc into the internal D drive.Thanks for your attention. I'm just a novice trying to address the problem and any suggestions are appreciated.

 

I had the same problems on my computer when I used dvd+r's to store stuff.
