Guys help, can anyone know what the error is?

A friend asked me to make a PC for him, his netbook broke down, I took up this business, because he himself does not know much about this, I certainly do not ice in programming and repairing a PC either, but I can reinstall Windows with BIOS. So my problem is this, I reinstalled Windows through my laptop, inserted its hard drive into my own, installed it, put the HDD in its place, and then ONE. Yet even the computer does not boot the PCIe error of the FE the Family the Realtek Controller software the Series v1.25 (04/19/11)
the PXE-the MOF: Exiting the PXE ROM drive

the Reboot and the Select Proper device not boot
or not boot the Insert media in selected not boot device and press a key

the whole head itself I broke it, I can't understand what the error is and what is it connected with, maybe what has burned out on the motherboard? I don't know what to do, who knows, please tell me.
