Fix

1. Run the Windows command prompt (cmd.exe) with Administrator privileges.

2. Run this commands to make Grub as the default boot manager:

   bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi 
   

3. Restart the computer, then you should see again the Grub menu with both Windows and Ubuntu.
