If your drive can read other cd's just fine, the drive isn't the problem. Also, give us the type of drive you're using.
Is there an error message that appears when you try to run halo? Give us what the message says, word-for-word. Was there an error when you tried reinstalling? Something like a corrupt file?
Check the disc for scratches and dirt like the other guy said.
