So far, no version of Windows runs off external drives. I have not read of a successful external drive install of Vista yet so you would be the first. Let me be clear that said externals are connected with USB or Firewire but not SATA.

i have a macbook pro (the first generation) with 2.16ghz core duo and 1gig of ram (hopefully upgrading that soon). i was hoping to be able to install vista on an external harddrive and somehow run it with bootcamp without installing it directly onto my laptop's on-board harddrive. any suggestions as to how to go about doing this?
