Make sure you've backed up everything important to you (and TEST YOUR BACKUPS) before proceeding to edit a partition table. Standard disclaimers for partition table editing apply: Mistakes made while editing partition tables can cause you to lose access to all the data on your drive. There's a chance you won't be allowed to relabel a drive that's in use (editing partition tables of drives is considered dangerous, especially when in use) so you might have to make sure none of that USB drive's volumes are mounted when you try to do this.
And of course, replace disk1 with the proper disk device identifier for your USB drive, as I said before. You should replace 2 argument of the -i option with the actual index value for the correct partition, as told by the index column of the gpt.show command output from your system. Note that I assumed that the Mountain Lion partition was at "index 2" in the output of the gpt.show command above. If the command above confirms my hunch, you should be able to change those labels like this: sudo gpt label -i 2 -l "Install OS X Mountain Lion" disk1
Use diskutil list to determine the drive device number of your USB drive, and use that in places of disk1 in the command above. Note, your USB drive may not be disk1 on your system. See if this command shows you the same names that the boot picker shows: sudo gpt -r show -l disk1 The system is running, but it doesn't boot without the USB stick, then we have to install the bootloader (Chameleon), the essential kexts and the DSDTĢ- Install Chameleon-2.The Mac EFI BootROM boot volume picker may be reading the GPT labels for the partitions without looking inside the partitions and parsing the HFS+ volume format to find the name the volume calls itself internally. * If you have problems in installation with the message "Mac OS X can't be installed on this computer", replace the file " OSInstall" in the folder System/Installation/Packages by this.Īfter the installation, boot the USB drive again, but in Chameleon menu choose to boot the HD. With the installer USB ready, boot it and install Lion to an HD partition. and select the USB drive as destination, or they will be installed on the running system. Remember to click on Change Install Location. Run the installers " Extra Lion" and " Chameleon RC5".
Copy the files to the Packages folder created previously.
