Yesterday, we discussed reports of Microsoft and the OLPC project working towards a dual-boot version of the XO laptop. Now, BetaNews tells us that Microsoft has issued statements denying such plans. The software giant has also reaffirmed their intention to develop a Windows-only version of the laptop. Microsoft's statement to BetaNews had this to say: "While we have investigated the possibility in the past, Microsoft is not developing dual-boot Windows XP support for the One Laptop Per Child's XO laptop. As we announced in December, Microsoft plans to publish formal design guidelines early this year that will assist flash-based device manufacturers in designing machines that enable a high-quality Windows experience. Our current goal remains to provide a high-quality Windows experience on the XO device."
