    Windows 10 Pro 64 bit

    Windows 10 CU destroyed my second S.O. (0xc000000e winload.efi)

    I am a little crazy now.

    I just updated from Anniversary to Creators via Windows Update.

    Everything seem to be OK.

    In my system I have TWO Windows 10.

    The second is HIDE from the first (simply hidden letter).

    I tried to launch the SECOND Windows 10 (still Anniversary) and... cannot boot.

    So I went in the disk manager and... there is the partition, there is the label but... ZERO BYTE!!!

    Please, tell me what I can do!!!

    I cannot believe that CU destroyed the dual boot of my computer!!!

    I just discovered that the data is still there. Luck!

    But, what is the easiest way to repair the dual boot? It is possible from Windows itself?

    I find some command lines to do but they are related to MBR but I have a GPT disk.

    I ran Macrium USB.
    I did "FIX BOOT".
    It found nothing.

    Than I ran DISKPART and I assign letters the each disk with an OS.


    Then Macrium find all the Win10 installation.

    I did FINISH and it REDO the BCD.

    So I try to launch the SECONDARY Win10 (anniversary) and it WORKED!!!

    But after a REBOOT it was down again with the same error.

    The FIRST Win10 (CU) works Always.

    I don't know what to do.

    If in the bios I select BOOT MENU (F9)
    - Launch EFI FILE
    - HD (only one is selectable)
    - BOOT
    - BOOT64.EFI (not the correct name)

    I can run my SECOND OS!!!

    But If I reboot again that error.
