AE error says on the screen "Reboot and select proper boot device or insert boot media in selected boot device and press a key" I looked up the error in the manual and it says it's a legacy boot event error. If I insert windows 7 into the computer and boot it up etc I can get it to the point of where I need the hdd because apparently that is not being detected. I can also access the bios but in there again the hdd is not being detected. Any help would be greatly appreciated and I can list the specs and parts I used if you need that.
