Repair Windows EFI system partition from linux live OS

As part of my project I am working on a ubuntu based live os that can be used as system rescue disk for linux as well as windows.



Basically it will be used as a rescue disk in case of boot failures.



This is working fine for linux systems.



I want to add the same feature for Windows as well.
The problem is recovering EFI based installations. I am not able to recover the EFI system partition from the linux env. especially the commands like





bcdboot



bcdedit




will not be working from linux.



Is there a linux replacement for this commands or is there a way of creating the Windows EFI partition from ubuntu.




Or does anyone knows about the files and flags that need to be set in the EFI System partition for the system to boot.
