Transporter to create WinXP VM

Hi,

Having read the guide on using Transporter to create a VM, I want to use this to create an image of my latop running WinXP SP2. I have read that the original Windows install disk will be required when first using this VM within Parallels. Is this correct? If so is there a workaround as my system was not supplied with the original disk, just a separate restore partition.

A quick additional question, if I may. On a new Mac with a clean install of Leopard, do I just download the newest trial software available on the site or do I specifically have to download version 5160?

Regards,
Darren
