Thanks for the reponse.
Ventanas: surely if having xp was a pre-requisite for installation it shouldnt let me install windows 7 at all? I still have the orig XP disc so i just thought i needed it to qualify the license. Its a full XP Pro (though 32 bit)
rdave13: option 4 looked good but too late now. In his initial warning above optoin 1 he does say they allowed you to install win 7 without having to install xp first. Not too sure why option 1 isnt usable.
