10.5: Install OS X to a different volume without rebooting
Authored by: appleguru1 on Dec 08, '09 02:49:56PM
@ Dr Happy Mac: I just did a Leopard install to an APM formatted firewire disk from my Macbook pro running Snow Leopard using OSInstall.mpkg.... It worked fine. You are correct though, I had to bless the CoreServices folder to get it to be bootable:

sudo bless --folder "/Volumes/VolumeName/System/Library/CoreServices" --bootinfo --bootefi

10.5: Install OS X to a different volume without rebooting

Thanks for the hint. Did all these, but in the end, my MacBook Pro wouldn't boot from the Leopard partition. It simply ends up in an infinite loop of restarts.

My hunch is that it should be related to the EFI firmware upgrade from december or so, when we've been updated to the 1.8 version of EFI and to the 3.0 firmware version of the superdrive. That's probably why I'm not even able to boot from the Leopard installation disk.

However, I haven't been able to test this hunch because I was not able to downgrade my firmware to its previous state.

Any ideas, hints... whatever highly appreciated.

PS: Thanks again for teaching me how to be a --folder-vicar :P

I can also confirm this trick doesn't work for Snow Leopard! Had to do it the normal way, boot from DVD then it will boot.

Hey, I just used your command with an added "--verbose" tacked onto the end. It works great, so I put it into an AppleScript app (see my other post). You select your volume from a list and enter your password. Your little command does the rest. Thanks for your help.
