Convert a drive from Apple Partition Map to GUID
Authored by: rawhead on Oct 30, '07 08:35:36AM
Well, not to be an attention whore, but I don't see how this hint is much different from the one I submitted

Although I didn't get into the details about using the backup software (I used Carbon Copy Cloner instead of SuperDuper!).

Anyway, that's not why I'm posting this. I figured out a definitely quicker way of doing this whole process (only AFTER I'd done it pretty much the same way). This will work so long as you don't need to "Upgrade Install" but are fine just doing an "Archive and Install" (which I would suggest to anybody upgrading anyway).

1. Make a clone of your HDD to an external drive using your software of choice (CCC, SuperDuper, whatev).
2. Use your Leopard DVD to boot your Mac, partition using GUID, and go ahead and do a clean install of Leopard
3. Once installed, go into /Applications/Utilities/ and run Migration Assistant.
4. Use Migration Assistant to migrate your user data over from the external HDD with the system clone on it.

This will cut down on the time it takes to re-clone your internal HDD, which, for me and my 100GB of data, took HOURS.

All these moments will be lost in time
Like tears in rain.
Time to die.

Convert a drive from Apple Partition Map to GUID

Not sure why any of this is a hint. You want to do something to the drive that generally requires blowing away its contents. Move it to another drive before you do that, then move it back.

What would be great is if we could find a way to change partition table formats without requiring those steps or ending up destroying the contents of a drive. That would have helped me this past weekend while trying to install Leopard.
