No Cd Writer What Do I Do?

please i need help with my computer.
My computer does not have a cd writer but I have a burner.
Yet I Find it difficult to burn into a cd. Each time I try, the information
displayed is "no cd found or no device found" please what do i do.
I really need to transfer some of my documents and movies to cd.

And it's not cost, you can afford a used one.

HOW DO I GET ACD WRITER,HOW MUCH DOES IT COST,
IS THERE ANY WHERE SOMEONE CAN DOWNLOAD IT FROM THE INTERNET

  Endure, you know what? when you get to the market, tell them to give you external cd writer. so, you can just use USB cable to connect your newly bought cd writer to your system without opening or removing the cover of your system. Connect this new cd writer to your system using USB cable and also connect the power adapter that came with the cd writer to AC outlet then to your cd writer. Power on your system and install the software that came with the cd writer! You can now use your new cd writer to write your document to the cd.

NOTE: The cd writer must be connected to the back of your system (USB Port) and you must use the AC adapter that came with the cd writer to power the writer ON and place the writer beside your system without opening your system each time you want to use the writer to writer your document to cd. Don't forget to switch on the cd witer pleeeeeeeeese.
