Ok so for over a week now I have been having similar problems with Windows 7, and I'm hoping someone will help me cure this today. I have a p8-Z77-v-LX Board, Brand new, A Brand New Seagate 1 TB Drive, and all of my other components are brand new as well. When I attempt to Load Windows 7 it does not see the drive. I know the drive is working because while trying to find a solution I have read Online that you should reformat the drive itself. I placed it into my old system, formatted it with Windows "NTFS by default I believe and still I have the same results. The Bios See's it aswell. the bios is this weird Asus Bios, but the Boot order is Optical Drive, Sata, USB. I have made sure it's set to AHCI and that Sata is enabled. I made this video to show exactly whats happening...
