When told him that it would cost him about $140, he was still open to the idea saying that if it would allow him to install Windows 8 on a VHD, it would be worth it. When I told him that there was a way he could do so, he was all ears. (As you know, the ability to boot from VHD is only available in Windows 7 Ultimate and Windows 7 Enterprise.) My friend has Windows 7 Home Premium installed on his computer and was saying that he would give anything for a way to add the Bootable VHD feature to his system so that he could experiment with Windows 8 and keep his Windows 7 setup intact. The other day I was discussing with a friend the benefits of dual-booting Windows 8 using a VHD (Virtual Hard Disk) as I wrote about in the article Dual-boot Windows 7 and Windows 8 using a VHD.
