PXE-E61 Media Test Failure Error for Intel® Desktop Boards Documentation
Content TypeTroubleshooting
Article ID000005740
Last Reviewed11/01/2017 What are you seeing?
The following errors display when your Intel® Desktop Board starts:

• PXE-E61: Media test failure, check cable.
• PXE-M0F: Exiting Intel Boot Agent.

Why are you seeing it?
PXE (Preboot eXecution Environment) is a boot environment that allows the Intel Desktop Board to boot up using a network interface, instead of booting from an installed hard drive. You can enable or disable PXE boot in the BIOS.
If PXE Boot is enabled in BIOS, the PXE-E61 and PXE-M0F errors can happen when both of these are true:

• A bootable hard drive is not detected.
• A network cable is not connected to the Intel Desktop Board.

How to fix it
If a drive is installed Check that the drive is detected in BIOS:

1. Press F2 during boot to enter BIOS Setup.
2. Go to the Boot menu.
3. Check the Boot Drive Order.
4. Press F10 to exit BIOS Setup.

If Boot Drive Order shows No Boot Drive:

• Check that the drive is properly installed in the computer.
• Try installing a different known good drive.

If PXE Boot is enabled in BIOS To check the BIOS option:

1. Press F2 during boot to enter BIOS Setup.
2. Go to the Boot menu and check for Boot to Network.
3. Press F10 to exit BIOS Setup.

If you do not plan to boot to a network, disable this option.

If you do want to boot to a network, check that the network cable connection is working properly.

READ THIS CAREFULY.

The error PXE-E61: Media test failure usually means the hard disk has failed or the hard disk needs re-seating or the disk controller is faulty. First - re-seat the hard disk and reboot the computer. If the computer does not boot up then reboot and go into the BIOS configuration to see if the BIOS detects the hard drive. If it doesn't detect the hard drive then it could be faulty. Next - to check if the hard drive is faulty, remove the hard drive and insert it into an USB hard drive adapter and connect it to a working computer's USB port. If this computer cannot see it as an USB mass storage device and you cannot open the various folders and files on this drive, then this confirms the hard drive is faulty. Then the hard drive needs to be replaced in the computer/laptop, Windows installed and the computer or laptop's device drivers plus your programs etc. to get a functioning computer/laptop again.

sounds like a driver issue try to go to toshiba's website and download the latest drivers for the NIC card.

your e-machine is set to boot from the network (PXE = Netboot)

go to your BIOS and make sure you boot from your hard drive

Save your self a lot of reading, do this first.
Check in BIOS rom for start up sequence and check if there is an asterist (!) in front of the hdd. If there is, it’s disabled. Select the hdd and press shift key plus “1′ This removes the ! and you can then use the hdd to re-format or….

you have a failed hard drive and will require a replacement.
