I have a brand new HP Envy dv6 with windows 8 on it from the factor. I have some software that is only available in Windows 7 with upgrade to windows 8 versions 6 to 12 months off. I figured no big deal, I've done dual boots before. Well it's different now. I made a partition, formatted it NTFS. So far fine. Stuck in a brand new never used windows 7 disk and tried to run it. Comes back with message that "Windows cannot be installed to Disk 0, Partition 5." Click on further details: "the selected disk of of the GPT partition style" Any idea what I can do. Called HP twice --- support says "we do not support dual boot". When pressed on this issue, they had no idea what to say when I asked: "Are you telling me that this machine and software is incapable of doing dual boots, or are you telling me you technical support people are not permitted to give advice?" These folks were overseas apparently and had no idea of what to tell me, they just were rattling off the company line and had no idea how to tell me what I was asking. Appreciate any advice you may have. If you are in any kind of business, wait at least 2 years before you even consider bringing Windows 8 in. There are way too many headaches --- constant interface complaints from users being the first thing you will encounter. Is HP the bad guy here????
