Yes, I know this question maybe has asked often. I searched a lot everywhere and really tried to fix it without annoying you, but I couldn't fix it with boot repair with entering in Ubuntu with a test Version.
So, I installed Ubuntu after I had Windows already everything was fine. I set up Ubuntu really nice I was happy then it happen Windows got full of Bugs and I had to reinstall it. So, it destroyed GRUB and I can't enter Ubuntu any more... the extra thing I have done: I used GParted and formatted the partition on which Grub was installed. So I need help. How do I install only the GRUB the thing that lets me choose what to boot and to choose Ubuntu. When I tried Boot Repair it says I have to deactivate Secure Boot. I deactivated it and it still didn't work.
Best would be if someone would help me get a finished GRUB Copy and Paste and format the partition into the right format to then select it from Windows with something like this:
bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi
