    I thought I remebered being able to change the drive designation for bootcamp?
    Bootcamp defaulted to "windows" as the name for the drive, I'd like to rename it if possible. I'm adding another windows boot device this weekend and want to be able to designate the names of the drives in the bootcamp drive selection screen.

    PS, I'm not talking about renaming the drive itself but what bootcamp refers to it on the the OS selection screen.

    Actually, you are talking about renaming the drive itself. The label in the GPT partition map is what MacOS X calls the volume everywhere (Finder, Startup Control Panel, etc..). The label on the MBR is what Windows will call it (same deal there, everywhere uses the same values). The only odd duck can be the EFI chooser screen (what you get when you hold down option a boot), that actually uses a pre-rendered image as the label, and in weird cases this can get messed up (in which cases it defaults to a not-as-nicely rendered version of what is guesses is the name). Using the "--label" option in the "bless" command can get you around this (or into custom setups).

    Executive version: rename it in the Finder and you will get what you want.

    Edit: I should have mentioned that MacOS X does a good job of keeping the EFI partition map and the MBR in sync, so I have never seen those labels out-of-sync.

    That may the the issue, I used a script to modify my mbr to use AHCI drivers in windows.

    The EFI chooser screen shows "windows" regardless of what the drive is actually named. My only concern is when I set up a second windows boot drive (my SSD OS drive) that they both will be named "windows" on the boot screen.
