MacOS discs often have dual filesystems -- one ISO-9660 and one HFS or HFS+. When you view such a disc in most non-Mac OSes, you'll see the ISO-9660 filesystem, which may give you access to few or none of the HFS/HFS+ files. This certainly seems to be the case with the Hazard disc; on my system, the ISO-9660 filesystem totals just 192KB in size, but it does install correctly, and in Linux (or OS X, of course), I can mount the HFS+ side and see 4.4GB of files.

Thus, I recommend you try booting the disc and see what happens. If you can't boot it, then post back with details about what happens when you try.
