I am trying the dual boot of the same drive again. The problem is that STUPID PDF guide i used said that there has to be a 60MB partition.
But then it shows a 64MB partition when installing MorphOS.
When i try and click on the partition to install (the 60MB) like it says in the guide i get a "Invalid partition Layout!" and some crap about the sector range.
This is dumb! I followed the instructions perfectly.
I was able to successfully install MorphOS and OS X on a G4. The problems I encountered were accidentally formatting the drives in HFS Extended instead of Standard. Once that was done properly, I was able to mount and format each drive accordingly and run the install. The only other issue I encountered was to make sure DH1 (not DH0/Boot) was bootable.
