More help needed with Halo

I have backed up my CD to iso and burnt a backup using Alcohol 120 when I attempt to install I get the message “Halo encountered a disk error while writing to the file C:…\ make sure your hard disk is not full and the file not in use”

Any clues? is this just a bad iso or is this some form of copy protect/

I suggest you dump the ISO and re-image the Halo disc using Alc and its native format, depending on your reader/writer you may need to slow the writing speed.

Please don’t crosspost. The Newbie one will be closed.
