Just because this article was written for slightly more informed people, doesn't mean it wasn't worth writing. how ignorant! #2 Court Kizer says:

I've asked about and haven't gotten any clear answer...Is there any difference in the ability for an intel mac to identify/mount a drive via firewire vs. usb...could it that it can mount via usb, but not firewire if it is APM not GPT formatted? Any thoughts welcome.

If your partition or hard drive is partitioned for 4 partitions and they were originally done on a non intel based machine can disk utilities re format with the GUID scheme? I have to assume not but never hurts to ask. Guess I should have left half the drive "free" then I likely could have had 2 schemes on the drive. I want separate boot images so I can have an external drive boot whatever Mac I need - intel and no intel machines. Thanks folks Bill Hi,

So what about an Intel Mac's internal drive? Is there any way to explicitly force GPT partitioning on it? Disk Utility is totally mum on the subject, as described in Jonathan Rentzch's article. I don't have a 2nd intel mac so target disk mode won't help me here (the 2nd PPC mac shows the options button as described in your article, but GUID Partition Scheme doesn't show up as an available config since a PPC Mac can't understand it anyway). You can probably figure out what I was doing to get the internal drive in a non-GPT state ;-) Fantastic and informative thank you. So what about an Intel Mac’s internal drive?

(I also droped Carbon Copy Cloner and TechTool Pro on it) I then used disck utility to repartion it as follows: instead making 4 partitions (Using PC Partion Scheme), (A) 50GB FAT32 (I plugged it into my PC and Converted it to NTFS), (B) 50GB Apple Partition, (C) 100GB Apple Partion, (D) the remaining ~170GB Fat32 I then Recovered the image to the 50GB Apple Partion. I was able to boot the the (B) 50GB Apple Partition (using PC Partition Scheme) and am now in the process of Cloning my internal hard drive to the 100GB external Drive partion (Apple Formated) All the drives are visable on the Mac (although the NTFS is read only). And I can boot to (B) drive. So it appears that the only limitation is that you have to install to a GPT, but you can boot from a PC Partion Scheme drive that has a recovered image on it.
