I have installed Windows, after that I have installed Ubuntu. I logged in to Ubuntu, everything was ok. Then I logged in to Windows and after that Ubuntu boot manager was gone, I couldn't get into Ubuntu. In order to fix this, I clicked something stupid in Windows like "Solve problems with booting" which probably made the situation worse. I can't boot to Ubuntu, it automatically loads Windows. I can't even go to Bios because Windows is so stupid.
I created something like this with Ubuntu Boot-Repair. They told me to share it with you:

sudo efibootmgr -v
and then to delete:sudo efibootmgr -b XXXX -B
