Boot from USB?

Hi all, I have a macbook pro and I would like to boot of an usb drive. I have an external hard drive with Debian on it with Grub as its boot loader. As I am new to macs normally I would just configure the bios to book from the usb drive. How do I do that in OSX?

Macbook Pro, Mac OS X (10.6)

You need to reformat the drive for Mac OS Extended Journaled and set up a boot partition for GUID. Then you can install an OS on that partition and it will boot. No bios, this is not Windows.

Can you refer me to any resources regarding that? At the moment I have grub installed on the MBR and first partition mounted as /boot which is using the ext2 file system. Which contains the linux kernel and all necessary things needed to decrypt the second partition containing the OS.

As I do not have too much knowledge on how the OSX boot process works, it will be difficult to attempt making this work… so anything would be greatly appreciated..
