Hey guys I'm having a problem getting Leopard working on a dual boot with windows 7 on my Custom Built desktop. When I finish the installer and it asks to reboot computer after installing my PC won't boot up any OS at (Not even on Windows 7) unless I repair Windows 7 with my Windows 7 disk so it boots up from Windows again, like as if when I install Leopard is causing Windows 7 not to boot either (Even though I installed it on a separate partition) Is there something I have done wrong? I've already made the separate partition as Fat 32 and changed the Sata drive to AHCI mode (for the installer to work). Does this require two separate hard drives for this to work properly or something or I am doing the installing part of it wrong?
