You are very welcome, i have different way of repairing system boot files stored at system partition .
You will have to use Diskpart command to find out the System Reserved partition assigned number.
The output of the below commands may display the name of the System Reserved partition as only System or ESP.
Type diskpart and press Enter.
Type list volume and press Enter.
Under the label row, find the label System Reserved and note its corresponding Volume number.
Now type select Volume=N and press Enter, where N is the Volume number you noted earlier.
Now type assign letter=w and press Enter.
Type exit and press Enter.
Type bcdboot C:\Windows /s w: /f ALL and press Enter.
Please replace partition letter C: with Windows installed partition letter. When computer boots into Windows Recovery Environment (WinRE) environment the drive letter assign to Windows partition may not be C: drive letter because Windows 7, 8 , 8.1 and 10 creates a separate system partition when it's installed from scratch. The system partition contains boot files WinRE assigns the system partition the C: drive letter and the Windows installed partition will be assign any other drive letter usually D: drive letter is assign to Windows installed partition. The Bcdedit /enum | find "osdevice" command can be use to find out the drive letter of the Windows installed partition the output of the Bcdedit command is similar to this osdevice partition=D:. The drive letter after partition= is the drive letter of the Windows partition.
