The instructions on boot-repair report tell you to boot into Windows (as you do now by changing boot order) and then:

For example you can boot into Windows, then type the following command in an admin command prompt:  
bcdedit /set {bootmgr} path \EFI\ubuntu\shimx64.efi  

Do this from Windows and then if it doesn’t work revise your question with current status / new issues.


Also note boot-repair created 7 custom entries to boot Windows and Ubuntu from UEFI. In my experience they won’t all work. After you fix the booting issues see this answer:
