Okey this morning I was greeted by this message when I wanted to start my laptop.
Intel UNDI. PXE-2.1 (build 082)
Copyright (C) 1997-2000 Intel Corporation
For Realtek RTL8101E/8102E PCI-E Ethernet Controller v1.09 (080602)
PXE-E61: Media test failure, check cable
PXE-M0F: Exiting PXE ROM.
Operating System not found
After that I've reinstalled my OS, Windows 7 by the way and everything worked fine for next 6 hours or so, then it froze. After that I turned it off and same message appeared when I wanted to start it again. What am I missing here?
