I have the same problem. My new MB is ASUS P4P800 Deluxe - much better quality than my present MB. I have identical 2 HD's - recently cloned from one to the other - and OEM ver. of Win XP Pro without a CD. Can the move be made to the new MB using Files & Settings Transfer Wizard without using a Windows CD? How? If I have to obtain aa XP CD does it have to be non-OEM?
