 Intel® NUC errors

Why are you seeing it?

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. You can enable or disable PXE boot in the Intel NUC 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 NUC. 

How to fix it

If an internal drive is installed

Check that the drive is detected in BIOS:

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

If Boot Drive Order shows No Boot Drive:
  • Check that the drive is properly installed into the Intel NUC.
  • Try installing a different known good drive.
If you are booting to an external USB device

Try the following:

  • Be sure the external USB device is a bootable device. You can use an application like Rufus* to create a bootable USB device.
  • Make sure the USB device is fully connected.
  • Connect the USB device to a different USB port on the Intel NUC to make sure there is not 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.

  1. Press F2 during boot to enter BIOS Setup.
  2. Go to Advanced > Boot > Boot Configuration.
