[ubuntu-in] Slightly OT - Booting Multiple Distro's of External USB HD

[ramnarayan.k at gmail.com]

Hi

Have a dual boot machine. Was wanting to install some other distros on 
an external (usb) hard disk.

First is this possible (am guessing if the machine is enabled to boot 
from usb device it should be)

Second - where would the grub loader for the distro(s)installed on the 
external usb device be stored - again am assuming it will be along with 
the main grub loader resident on the machine. If so would it matter 
during boot up if the said device is not attached.

lastly - majorly OT - can a legal version of M$ wincedoze be shifted 
onto an external hard disk and can it also boot off the external hard disk

thanks
