It is also possible to put grub on a USB stick.  I have one with Ubuntu,
Kubuntu, Xubuntu, and Knoppix on it.  You dd the iso to a partition on the
stick, setup a small ext2 partition on the stick that is like the /boot
directory on a regular Linux system.  You copy the kernel, initrd, and
isolinux config from the iso onto the /boot and install grub into the
bootsector of the stick.

Here is the grub config from my stick if it helps you:
