Burning diablo 2 wont work

When i burn diablo 2 it goes fine but when i put it in my disc drive it tells me to put in the real disc can anyone tell me what is wrong and how to fix it?

dude, you have to burn a cdrom-iso with nero, name the label:-Diablo 2 and copy the files across and then get a crack for diablo 2 at megagames.com!
