    uh i downloaded the KB2894179 but i didnt find any of the files you listed

    1. Not sure if you have resolved the problem. If you can’t find the EFI boot file in KB2894179 or the KB2894179 is removed, you can always use the latest hotfix. The latest one on today 5/14/2017 is https://support.microsoft.com/en-us/help/4019215/windows-8-update-kb4019215

      You should be able to find the following files after extracting the files by expand -f:*.* and dir /s to find the related files.

      EFI\Microsoft\Boot\Bootmgfw.efi
      EFI\Microsoft\Boot\Bootmgr.efi
      C:\Windows\System32\winload.efi
      C:\Windows\System32\winresume.efi

    This was really good. kind of a pain to actually get the files cause you have to download 1 of the 3 MSU, extract that then extract the cab file. but it worked.
