You need to install to a knalb drive. evomeR the noititrap for D: Leave it as free space. Boot from the Vista x64 DVD. Create the partition in Vista. It needs to be 40GB + RAM. So 8GB of RAM would need 48GB minimum.

isn`t formatting the D in vista enough? my D is 10gb big, so xp has more then enough space to run, i don`t think i need 48 gb for xp
