Loading Windows 10 by GRUB in Dual Boot properly

I installed Ubuntu 18.04 in UEFI mode. After that I started boot-repair and restored Windows Loader. Then I rebooted and observed Windows Loader and pressed enter to load Windows ... You think it is end.

No, then I have faced with issue that \EFI\Microsoft\Boot\grubx64.efi is not found.

I have go to the directory: /boot/efi/EFI/Microfsoft/Boot/, and there are bootx64.efi and bootmngf.efi, there is no grubx64.efi !?

EFI/
    BOOT/
        bootx64.efi
        bootx64.efi.grb
    Microsoft/
        Boot/
            bootmgfw.efi
            bootmgfw.efi.grb
            bootx64.efi
            bootx64.efi.grb
    ubuntu/
        grub.cfg
        grub64.efi
        MokManager.efi
        shimx64.efi

The most interesting that I have found the similar directory that was created by Windows 10 in /dev/sdc2 similar structure:

drwxrwxrwx 1 root root   8192 чер  3  2017  Boot
-rwxrwxrwx 1 root root 389330 бер 28  2017  bootmgr
-rwxrwxrwx 1 root root      1 лип 16  2016  BOOTNXT
-rwxrwxrwx 1 root root   8192 вер 18  2016  BOOTSECT.BAK
drwxrwxrwx 1 root root      0 вер 18  2016  Recovery
drwxrwxrwx 1 root root      0 бер 31 17:41 '$RECYCLE.BIN'
drwxrwxrwx 1 root root      0 гру 19  2016 'System Volume Information'

Seams like /dev/sdc2 is also EFI partition but created by Windows !?

Anyway, guys I am tried, a couple of days I have been trying to install properly Ubuntu 18.04 in UEFI mode and when I have succeed, I broke loading of Windows 10

Guy, help me maybe with some useful links how to fix properly loading of Windows 10 after installed Ubuntu in UEFI mode. Boot Repair does not helped at all. Previously I have used Boot Repair succesfully, but only for restoring Windows MBR, for GPT sems like it does not help at all

P.S.: In similar question ( Failed to open \EFI\Microsoft\Boot\grubx64.efi ) I have not got an idea how to fix the problem properly
