Hi I'm sorry if begging or asking is a problem, but I need help with something. My eMachines D520 laptop will not boot up. Here is what the message says: Intel UNDI, PXE-2.1 (build 082) Copyright (C) 1997-2000 Intel Corporation For Realtek RTL8111B/8111C Gigabit Ethernet Controller v2.15 (080320) PXE-E61: Media test failure, check cable PXE-M0F: Exiting PXE ROM. No bootable device -- insert boot disk and press any key. If anyone has a solution for this I would be very grateful. Thanks!
