No EFI Boot files created on EFI part (ESP) and no BOOT-OPTION

I Have installed FydeOS twice, but there is no boot-option.
No BOOTMGR kind of thing in boot sequence.

There is no other question like this in this forum.

The main OS files, on the OS Partition, are installed (the folders like boot, lost+found etc)
refind also doesnt install. also installed manually, but didnt work.
