either your executable is corrupted with regards to the expected format or your bootloader is expecting a magic number to be present in the first part of your executable.

for example, with GRUB the magic number must appear within the first

8KB. this is done by putting the magic number and entry point in a specific section (let's call it ".init") and update the linker script so that section ".init" is always the first to appear in the executable file.
