When I try to install Halo 1 for the PC at 88% it will say "Halo Setup encountered a disk error while writing to the file C:\Program Files\Microsoft Games\Halo\Gearbox.bik. Make sure your hard disk is not full, and that the file is not in use" I checked to see how much space I had and I more then enough and no other files or programs were running my disk isnt scratched at all sadly the Warranty Expired so I cant return it does anyone know how to fix this?
