Can't find where to put a cd into my Lenovo desk top?

Does the machine have an optical drive? Many new machines don't have them any more.

You can buy a USB connected one if needed.

Maybe there's no place to put it. Which desktop do you have?

If you can't find it then there's none.

It doesn't have a cd player

If it doesn't have an optical drive, buy an external unit.
