Something's wrong when I insert a CD

[gilbert555]

When I insert a cd into the computer, it doesn't work. I want to write some files to the cd, but when I click on it, it says to insert a cd. What should I do?

Does it recognize any cd?

If you insert the Win install disk in the cd and reboot with cd selected before hd in boot sequence, does it boot the install disk?
