I have just built a computer with an msi Z87-G43 8gb ram kingston (4gbx2) and 1TB of hard drive. When I turned it on I went into BIOS and had arranged the boot device priority but when I reboot I get the message "Reboot and select proper boot device. Or insert boot media in selected boot device and press a key" I have rearranged the devices many times but still the same error. I have looked it up but I can't find a solution. I need to install Windows 7 Home Premium. Please Help!!!
