If it's an original DC GD-ROM disc you won't be able to run it on any PC because no CD/DVD-ROM it's compatible with that format.
If it's a burned ISO, make sure you got the DC bios files (dc_bios.bion , dc_flash.bin) and place it on the same folder as Chankast.
Also if the ISO/burnt CD it's not self bootable, you'll need the Utopia Boot Disc version 1.1.
