PXE: Failed to read PXE settings. The system cannot find the file specified. (Error: 80070002; Source: Windows)

Issue :You try to PXE boot a computer to deploy operating system through SCCM  but it throw the error :

PXE-T01: File not found
PEX-E3B: TFTP Error – File not found

Upon investigating  you find that smspxe.log shows this error:

“Failed to read PXE settings.
The system cannot find the file specified. (Error: 80070002; Source: Windows)”

This error comes when boot images and related files are not ready on SCCM server  or Windows Deployment Service is not running on PXE service point role.

Solution:
1. Take ownership of this folder and delete all content : C:\Windows\Temp\PXEBootFiles

2. If that doesn’t help delete the boot images and re-create them
