Could you extract the file \Windows\Boot\EFI\bootmgfw.efi from your .wim image and post a copy of it somewhere?

I've extracted and uploaded it to mega:

Thanks. That file is definitely a 32-bit UEFI executable:

Code:

[mcb30@squirrel ~]$ objdump -x ~/tmp/bootmgfw.efi
/home/mcb30/tmp/bootmgfw.efi:     file format pei-i386
/home/mcb30/tmp/bootmgfw.efi
architecture: i386, flags 0x0000012f:
HAS_RELOC, EXEC_P, HAS_LINENO, HAS_DEBUG, HAS_LOCALS, D_PAGED
start address 0x10013b80

Characteristics 0x2102
        executable
        32 bit words
        DLL

For reference, here's the equivalent for a 64-bit UEFI executable:

Code:

/vault/images/efi/x64/Shell.efi:     file format pei-x86-64
/vault/images/efi/x64/Shell.efi
architecture: i386:x86-64, flags 0x0000010b:
HAS_RELOC, EXEC_P, HAS_DEBUG, D_PAGED
start address 0x0000000000000240

Characteristics 0x2e
        executable
        line numbers stripped
        symbols stripped
        large address aware

A 32-bit UEFI executable cannot be loaded on a 64-bit UEFI system. This fully explains the error that you were seeing.

The question then becomes why would there be a 32-bit UEFI bootmgfw.efi in your apparently 64-bit WIM? I wonder if your toolchain is somehow including both 32-bit and 64-bit versions of bootmgfw.efi, and wimboot is erroneously picking up the 32-bit version. Could you post a full list of all *.efi files present within the problematic WIM?

Thanks,
