We use external FW/USB drives as portable diagnostic and installers and even though the partitions are named and have a custom icon, they show up as "Mac OS X" with a generic USB/FW icon when option booting.
How do I make the names and icons "stick" so they appear as I named them?
In System Preferences I've tried setting a partition as the startup disk and restarting when prompted; no change.
My current drive is formatted GUID and is broken into 9 partitions when viewed in Disk Utility. 8 are bootable and 1 is not. The retail partitions are the DVD installers or the Mac App Store Installers used to re-image new hard drives. The diagnostic partitions are a working OS with diagnostic utilities (DiskWarrior, Drive Genius, etc.) installed.
