An open engineering effort to bring Windows 11 ARM64 to Apple Silicon. Direct booting, without macOS running as the host. Windows has not booted yet.

The lines are the EFI shim, not a Windows console.

One 14-inch M3 MacBook Pro, 2023, has reached the shim.

m1n1 and U-Boot have executed there. The AArch64 shim loaded a Microsoft EFI image, machine AA64, and traced firmware services. Windows Boot Manager has not been shown to finish. There is no setup, no desktop, and no public installer.

The chain stops at the shim.

Apple iBoot
Verified
Apple's bootloader on the test machine. Not a BootCampARM component.
m1n1
Verified
Stage 1 and stage 2 have executed on the primary M3 test machine.
U-Boot / UEFI
Verified
U-Boot supplies the UEFI environment used to launch EFI applications.
BootCampARM shim
Verified
The AArch64 shim runs, loads a Microsoft EFI image, and traces firmware services.
The record stops here.
Windows Boot Manager
Not yet verified
StartImage is attempted. Initialization has not been verified.
Windows Loader
Not achieved
The Windows loader has not been shown to run.
Windows 11 ARM64
Not achieved
No setup, desktop, or completed installation.

M3 / UEFI execution trace

Shim console lines. Not a Windows kernel log.

Line notes

SHIM ENTRY 7: efi_main of the current diagnostic shim started and printed to the UEFI console.
LOAD IMAGE 0000000000000000: LoadImage returned 0, which is EFI_SUCCESS. The Microsoft EFI image was loaded. It had not yet been started.
MACHINE 000000000000AA64: PE machine field AA64 means IMAGE_FILE_MACHINE_ARM64. The loaded image is an AArch64 EFI binary.
ENTRY HOOKED: The shim patched the loaded image's entry so later lines come from instrumentation.
TRACE ON: Boot Services and Runtime Services hooks are installed. Later service names are those hooks firing.
STARTING WINDOWS: The shim's own label immediately before StartImage. It does not mean Windows Boot Manager finished starting.
WIN ENTRY: The hooked entry point began. Observed, and still under validation.
STP OK: The shim's entry hook passed its stack setup check and continued.
RESUMED: Control returned through the hook path. This is not a completed boot-manager handoff.
RT GetVariable: Runtime GetVariable was called. The variable name is omitted from this sanitized excerpt.
BS HandleProtocol: Boot Services HandleProtocol was called.
AP TYPE 0000000000000002: AllocatePages type 2 is the UEFI value AllocateAddress.
AP IN 0000000010200000: Address argument passed into AllocatePages. No claim is made about what resides there.
AP STATUS 800000000000000E: EFI status with the error bit set. The low code 0xE is EFI_NOT_FOUND. The allocate call did not succeed.
AFTER ALLOC: The AllocatePages hook returned and the shim continued tracing.

Experimental diagnostic trace from the BootCampARM EFI shim on the primary M3 test machine. These are shim console lines. This is not Windows kernel output, and it does not show Windows Boot Manager completing initialization.

Claims, one at a time

Full record

Not yet verified

Windows Boot Manager initialization

The shim calls StartImage on the loaded Microsoft image. A completed Windows Boot Manager initialization has not been verified.

There is no verified boot menu, BCD-driven handoff, or confirmation that bootmgfw.efi finished its own startup. STARTING WINDOWS in the trace is the shim's label for the StartImage call.
