    Intel® NUC errors

Note PXE (Preboot Execution Environment) is a boot environment that allows the Intel® NUC to boot up using a network interface, instead of booting from an installed hard drive. 

Why are you seeing it?

The PXE-E61 and PXE-M0F errors can happen in the following circumstances:

  • The Intel NUC is configured to boot to a network, but a network cable isn't connected to the Intel NUC. 
  • The Intel NUC can't find the Windows installation on the hard drive (The drive is not detected).

How to fix it

If you want to boot to a network drive:

  • Make sure the Ethernet network cable is fully connected to the RJ45 jack on the Intel NUC.
  • Try a different Ethernet network cable.

If you want to boot to Windows on an internal hard drive:

Step 1:

The BIOS Setup might be configured to check for a network drive. You can disable the network boot as follows:

  1. Press F2 during boot to enter BIOS Setup.
  2. Go to Advanced > Boot > Boot Configuration.
  3. In the Boot Devices pane, disable Network Boot.
  4. Press F10 to exit BIOS Setup.

    Disable Network Boot

Step 2:

Check to see if the internal hard drive is detected in BIOS Setup:

  1. Press F2 during boot to enter BIOS Setup.
  2. Go to Advanced > Boot > Boot Priority.
  3. Check to see what is listed under Boot Drive Order.
  4. Press F10 to exit BIOS Setup.

    No Boot Drive

If the Boot Drive Order shows No Boot Drive:

  • If you are using a 2.5-inch drive, check that the cable connections between the motherboard and the drive bay are secure.
  • Try installing a different known good drive.
  • Check to see if the drive is working—install it in a known good system.

If you want to boot to Windows on an external USB device:

  • Make sure the USB device is fully connected to the USB port.
  • Connect the USB device to a different USB port on the Intel NUC to make sure there isn't a problem with that specific port.
  • Check that you enable the USB Boot option in BIOS Setup:
    1. Press F2 during boot to enter BIOS Setup.
    2. Go to Advanced > Boot > Boot Configuration.
    3. In the Boot Devices pane, enable (check) USB to enable USB boot.
    4. Press F10 to exit BIOS Setup.

      USB Boot option enabled

  • Be sure that the external USB device is a bootable device. You can use an application like Rufus* to create a bootable USB device.
