Reboot and select proper boot device or insert boot media in selected boot device and press a key pops up on startup. I tried setting my boot order but the only thing that pops up in the boot menu is "Realtek pxe b04 d00" and "p2: atapi ihas124 f" and I changed the order of them and stuff and nothing happened, just keep getting the same reboot and select pop-up. I've tried to put in the graphics card disk (gtx 1070) and I don't think it read the disk. The disk drive will slide in and out so it isn't disconnected, maybe the problem is the hard drive, but it is connected to the motherboard.
