There is no way to initialize NixOS my system with uefi

I recently successfully install and run NixOS on my computer, but with a problem with no space in EFI partition I decide reinstall all the OS, so, when I reinstall the OS and reboot my computer I don’t have the button for select the OS in the grub (I don’t know the name but it’s that thing which allows you to select the operating system).

I use dualboot and when i reinstall again I didn’t get any errors but the problem persists.

If you have any solution or idea what happend please write it.
