No, XP is a lot harder because by design, it doesn't load USB drivers the same way it does CD drivers I'm not sure of the internals of it, but basically it's not a simple copy/paste job. I use that tool on msfn to add a parted magic iso to the install too, and my
acronis true image iso, can add W7 or Vista to the usb stick easily too So you get a boot menu asking you ...
