i just copied an iso file ...how do burn it to play the game?

Answer 1

Nero - or pretty much any other CD / DVD authorising software.

Open the application and look for "burn image file" - or something similar.

If you say what software you have we can be more specific.

Answer 2

You need a CD burning program such as Nero.
Put a blank disk in your drive.
Find the menu option to create a disk from an image.
Select iso as the file type.
Browse to your downloaded file and select it.
Burn the disk.
Now use it like any store-bought disk.
