Okay, so, I've had an ASUS for about four years (Intel Core i3, 64bits) (I don't know the exact Asus model, sorry) and since yesterday I've been getting this message whenever I start my PC:
INTEL UNDI, PXE-2.0 (build 003)
Copyright (C) 1997-2000 Intel Corporation
***JMicron JMC25X Gigabit Ethernet Controller Version (i couldn't pick the number)
PXE-E61: Media test failure, check cable
PXE-MOF: Exiting PXE ROM.The only "change" I've done in my computer recently was updating Itunes (but I have tried uninstalling it and the message still shows up). My computer STILL boots normally after this message shows up; it's not even slower or anything, the message simply shows up and then the computer boots normally.
Could you tell me if there is a way to make it disappear or if this may be cause for me to worry? (And please answer in the most simple way you can because my knowledge of computer hardware and software is like... 00000,00000).

Your computer is trying to PXE boot.
When you computer powers on the firmware (e.g. the BIOS or the UEFI) does several things and then hands over control to the OS. This OS can be located in several places, e.g. on a floppy, on a CDROM, on a harddisk or somewhere on the network.
Usually it will try several of these in sequence. E.g. first try to boot from floppy, it that fails because no floppy is present then try to boot from CDROM. If that fails move on to the next bootable device in the list.
Network cards can be bootable devices.
What happens in your case it that the network card is configured as a bootable device and that your system is configured to try to boot from the network before booting from your harddisk.
This is not something you general can set from within the OS. The change this you either need:
- To enter the BIOS/UEFI and change settings.
- Or use a program specially for your motherboard to change the BIOS.
- Or you have a failing battery and values in the BIOS are no longer maintained.
