How can I change the title of a boot image? I have an external Hard Drive with two bootable partitions on it. The first is an image of a Mac OS X 10.6 Install DVD, and the second is an image of a Mac OS X 10.6.3 Install DVD.

When I plug the hard drive into a Mac Mini, and turn it on holding down the Alt key, I get the option to select which boot device to use. However both my bootable images are named "Mac OS X Install DVD".

How would I change the name of the bootable image?

I have already tried changing the partition names but this has no effect.

Any ideas?

Note: I originally asked this on SuperUser, but upon discovering this site, I asked it here also.

This is an older post, but I came across it today and figured I'd share what I found.

The 'bless' command seems to make this work. First make sure the disk is mounted, find out which folder it is mounted to, and:

sudo bless --folder &lt;mount_path&gt; -label &lt;desired_label&gt;


For example:

sudo bless --folder "/Volumes/Mac OS X Lion Install ESD" -label "Lion Install"


Whatever you put for the label is what should show up at the choose disk screen when holding option during a boot.

Note that you'll probably want to do this in addition to renaming in Finder or Get Info just to keep them somewhat in sync and make them easier to identify in either case.
