The header is not correct. % file certmule.efi certmule.efi: PE Unknown PE signature 0x742e (stripped to external PDB), for MS Windows It is missing many fields, including the Subsystem. % objdump -x certmule.efi certmule.efi: file format pei-aarch64-little certmule.efi architecture: aarch64, flags 0x00000001: HAS_RELOC start address 0x0000000000000000 Characteristics 0x20c line numbers stripped symbols stripped debugging information removed Time/Date Wed Dec 31 16:00:00 1969 Magic 0000 MajorLinkerVersion 0 MinorLinkerVersion 0 SizeOfCode 0000000000000000 SizeOfInitializedData 0000000000000000 SizeOfUninitializedData 0000000000000000 AddressOfEntryPoint 0000000000000000 BaseOfCode 0000000000000000 ImageBase 0000000000000000 SectionAlignment 00000000 FileAlignment 00000000 MajorOSystemVersion 0 MinorOSystemVersion 0 MajorImageVersion 0 MinorImageVersion 0 MajorSubsystemVersion 0 MinorSubsystemVersion 0 Win32Version 00000000 SizeOfImage 00000000 SizeOfHeaders 00000000 CheckSum 00000000 Subsystem 00000000 (unspecified) DllCharacteristics 00000000 SizeOfStackReserve 0000000000000000 SizeOfStackCommit 0000000000000000 SizeOfHeapReserve 0000000000000000 SizeOfHeapCommit 0000000000000000 LoaderFlags 00000000 NumberOfRvaAndSizes 00000000 Move over all the linker script files from shim to properly build a certmule program that can be signed.
