Installing Suse on an external drive

Hiya: I am running SuSE v9 pro on my laptop & I would like to install it on a external USB 60 gig drive, and set up apache. I am having the worse time trying to install on an external drive and was hoping you all could offer some words of wisdom in my direction about the best way /least painful way to approach this. The windows/hardware people at this company tell me to GHOST a copy/image and then configure Apache. once installed. TIA Siobhan
