Make a new folder on u hard drive. ( name it COD or something like that ) Copy the hole dvd to u new folder. Some files can be hard to copy to u hard drive folder.!!! You must open u dvd and copy them manualy those files, that doesent want to be copyed. Hope u see my point. U must have all the files from u dvd to u new folder. When finish, start too install the game from u hard drive. ( Finish ) Now i can put in u dvd and play u game as normal. It worked for me so i hope it work for u too. Give me a hint if u get it to work too.
