Zorin not starting

as i said in the title for some reason zorin is not starting. I have duel boot, zorin and windows 11. I used Boot repair program and after a series of commands to put into the terminal, and after a while it generate this error:
"An error occurred during the repair.
Error: no grub*.efi generated for Zorin OS 16.3. Please report this message to boot.repair@gmail.com

Please write on a paper the following URL:

If you still experience boot problems, indicate this URL to:

You can now reboot your computer.
Please do not forget to make your UEFI firmware boot on the Zorin OS 16.3 entry (sda1 file) !
If your computer reboots directly into Windows, try to change the boot order in your UEFI firmware.
If your UEFI firmware does not allow to change the boot order, change the default boot entry of the Windows bootloader".

Can you please help me on what i need to do?

Thank you for your response. You mean choosing Ubuntu as the first boot in the boot sequence?
If that's what you mean, it is already Ubuntu as the first boot.

OP has stated "first boot", not confusion with "fast boot" from what I read.
But yes, secure boot and fast boot should be off nevertheless.
