What This Code Means
PXE boot failures indicate the firmware tried to boot from the network using PXE. This often happens when the boot order includes network boot and the system didn’t find a valid local boot device first.
Where Users Usually See This Code
- Enterprise-managed PCs with network boot enabled
- When the system drive is missing or not bootable
Why This Code Appears
- No bootable local device was found, so firmware tried PXE
- Network boot infrastructure is not available on this network
- PXE settings are enabled unintentionally
What Typically Happens Next
- The system cannot boot and may prompt to select a boot device
What This Code Is Not
- It is not an internet browser error
- It is not a Windows Update issue
Troubleshooting Checklist
- □ Verify the internal drive is detected and set as first boot device
- □ Disable network boot if not required
- □ If the system is managed, contact IT for PXE server requirements
Notes And Edge Cases
PXE messages are common when a machine is set to netboot in the absence of a valid local OS.
