Trouble with multiple installs

[Dragonsblood1987]

I'm trying to set up a clean install of titanium in another directory (to try another server), but when i mount the first eq ISO and run it, I only get the options to modify, repair, or uninstall my current one. For the sake of not screwing something up, i was hoping to get a step-by-step for creating a clean install before running anything. Any advice would be greatly appreciated!
