PXE-E61: Media test failure check cable


Upon booting your PC, the following message is being displayed:
PXE-E61: Media test failure check cable
PXE-M0F: Exiting Boot Agent

Why this message is being displayed: Some explanations

The PXE-E61(: Media test failure check cable) error occurs because the computer is trying to boot on a network device and fails. The computer will ask you to verify if a network cable is connected.
The PXE-M0F: Exiting Boot Agent error warns you that the PC is unable to boot and is exiting the PXE boot mode.


This error can occur for many reasons.

Case 1

The PC needs to boot on network device (which is rarely the case)
  • Solution:
    • Check if the network cable is disconnected or faulty. Either reconnect the later or use another network cable (RJ45).
    • This problem can also be due to a faulty network card.

Case 2

The boot sequence is not properly configured (BIOS) and the computer attempts to boot from a "PXE" network card. The boot sequence defines the order of the boot devices. The PC will first try to boot from the primary boot device and in case of failure it will switch to the next one.
  • Solution:
    • You have to go into the BIOS to change the boot sequence (the approach may be different depending on your motherboard model).
    • You normally have to press a key (Eg: Esc or Delete or F2 ...) or a combination of keys (Eg: Ctrl + F1 or Ctrl + F2 ...) upon starting your PC machine.

The BIOS is a very sensitive area and you should avoid making unnecessary modifications. **Take the time to read everything on the screen in order to learn how to navigate in the BIOS.

Case 3

The hard drive, its connections or the motherboard is faulty.

-The computer does not boot,
-The computer boot from time to time but produces BSOD (Blue Screen Of Death)
-The computer freezes randomly
-You hear a strange rattling from your computer
Why is the PXE error displayed?
Imagine the following (basic) boot sequence:
1 => HDD
2 => CD/Rom
3 => USB
4 => PXE

If your HDD is faulty and the PC won't be able to boot from it, it will try to boot from the next device (CD/ROM). If you have not placed bootable CD in your drive, it switches to the next device, until it reaches the PXE (or LAN) option. As result you will end up with the PXE error.

  • Open the computer, unplug your hard drive and clean the connectors and reconnect it.
  • If the above solution doest work, the problem can be due to a faulty motherboard or HDD.
