VMware Fusion

I have been installing a trial copy of VMware fusion and had problems installing my copy of Win XP. It got so far then said that it couldn't find a drive and then terminated the installation. I tried to uninstall Fusion but it would only uninstall the programme itself not the Virtual Machine which was created. I would like to clear the decks and start again. Where is the Virtual Machine? I cannot find it anywhere.

Any help would be appreciated

Thanks

Brian
