          By boot list, I am assuming the grub menu. The grub menu only knows about what is already installed on existing hard drives when the grub menu was set up. If you attach an external drive afterwards, grub will know nothing about it.



          The cleanest way to boot off of some other media is to use the boot menu in the firmware. Usually pressing the F12, F10 or some key like that while the machine is powering up will present you with a list of hard drives to boot from. You can select your external hard drive from there.



          Hope this helps.
