I have had my Sager laptop for about two and half years now. About 6 months ago a message popped up when I booted up my computer. It said: PXE-E16: Media test failure, check cable. PXE-M0F: Exiting PXE ROM. Reboot and select proper Boot device or Insert Boot Media in selected Boot device and press a key. I don't remember how I got passed it, but I think I just fiddled around with the boot order and waited a bit. Since then it has happened 3 or 4 times and I've managed to get past it doing the same thing. But this time I can't seem to get past it. I've changed the Boot order, disabled and enabled a bunch of random stuff, I'm stuck. My hard drive is MATSHITABD-MLT UJ260 and my network device is PXE BO3 DOO. Any help would be greatly appreciated, thank you.
