Your log said that you saw this: grub-install: error: filesystem on /boot/grub is neither HFS nor HFS+
I have no idea what the filesystem on /boot/grub might be, but it should be HFS or HFS+ for this to work. So, assuming you are using the blessed ISO and no other, what I would do is start fresh. eg, mount the drive from a different macOS system using Firewire mode, delete all the existing partitions on the drive using Disk Utility, and then reboot the system using the CD, holding down the “C” key during boot. After it boots, let it have the entire disc, and let all the defaults be the defaults. That should work. If it doesn’t work, time for a new log I guess.
