    First, re-create partition 2 to be EFI System, open Admin command and type:
    diskpart
    select disk 0
    select par 2
    delete par
    create par EFI =====> Re-create partition to be EFI System
    format fs=fat32
    assign letter=U
    exit

    Next, type:
    bcdboot C:\windows /s U: =====> will create a new BCD to boot from for new EFI System.

    REBOOT

    access boot menu, there will be 2 Windows Boot Managers, 1 for the first EFI just created, the other for the old EFI. Select the first one to boot from.

    Open Admin command again, type:
    diskpart
    select disk 0
    select par 6
    delete par override =====> this will delete the old EFI.
    exit

    NOTE: The order of Windows Boot Manager might be in reverse. If cannot delete par 6 (Old EFI) then reboot, select 2nd boot manager then try to delete partition 6 again.

    just read bcdboot /? reference... isn't it

    bcdboot C:\windows /s U /f UEFI ?

    ESP was created but
    bcdboot C:\windows /s U: (or with /f UEFI)
    not works, info is still Hidden in DIskpart list vol or None in 3rd party GUI partition programs

    You must have done something wrong or did not follow exactly what I posted above. If done correctly, you should see 2 EFI System partitions and both can boot into Windows. From Boot Menu, you should see 2 Windows Boot Manager

    Why did you use list volume instead of list partition ? you need to know which partition to delete.

    Try again. Use the first Windows Boot Manager to boot. Once in Windows, delete the second Windows Boot Manager.

    SOLVED !
    access boot menu, there will be 2 Windows Boot Managers, 1 for the first EFI just created, the other for the old EFI. Select the first one to boot from.
    just didn't realize what's actually access boot menu supposed to mean... it means get into bios firmware setting ! (press F2 of F10 or another Fn depends on H/W)

    Thanks so much. God blesses you.. ameen
