🪟 Windows on ARM Support

NEW: Complete infrastructure for running Windows 11 ARM64 on Raspberry Pi!

⚡ Quickest Method (New!)

Have a Windows 11 ARM64 ISO? Create bootable media in minutes:

# 1. Mount your Windows ARM ISO (double-click or):
Mount-DiskImage -ImagePath "Win11_ARM64.iso"

# 2. Run the automated extractor:
cd raspberrypi-firmware
.\tools\windows\extract-windows-arm-boot.ps1 -AutoDetectISO -DestinationPath E:\ -PiModel Pi4

# Done! Copy to SD card and boot your Pi

What it does:

• ✅ Auto-detects mounted Windows ISO
• ✅ Downloads latest Pi UEFI firmware
• ✅ Extracts Windows boot files
• ✅ Creates optimized config.txt
• ✅ Complete bootable media in ~10 minutes

Press ESC during boot to access the built-in UEFI menu!

Features

• ✅ Automated Boot Media Creation - One command creates bootable media
• ✅ UEFI Firmware Auto-Updates - GitHub Actions monitors and updates UEFI
• ✅ Hardware Compatibility Checker - Validates your Pi before installation
• ✅ Driver Management System - Automated driver installation
• ✅ Optimized Configurations - Pi 4 and Pi 5 specific configs
• ✅ Comprehensive Documentation - Beginner to advanced guides

Quick Start

# 1. Create boot media (on Windows PC)
cd raspberrypi-firmware
.\tools\windows\create-windows-boot-media.ps1 -DriveLetter "E:" -PiModel "Pi4"

# 2. Boot your Raspberry Pi and install Windows
# (See full guide for details)

# 3. Install drivers after Windows setup
.\tools\windows\install-drivers.ps1

Status & Limitations

⚠️ Important: Windows on ARM for Raspberry Pi is unofficial and community-supported

What Works: CPU, RAM, USB, Ethernet, Display (basic), SD/USB storage
What Doesn't: Wi-Fi, Bluetooth, GPU acceleration, Analog audio, GPIO
Performance: 2-3x slower than Linux, expect basic usability only

Supported Models:

• ✅ Raspberry Pi 4 (4GB+ RAM recommended)
• ⚠️ Raspberry Pi 5 (experimental, early BCM2712C1 only)
• ⚠️ Raspberry Pi 3 (not recommended, too slow)

See documentation for full compatibility details and workarounds.

Repository Contents

A rough guide to this repository and the licences covering its contents is below (check the appropriate directories for more specific licence details):

• boot:
  • start*.elf, fixup*.dat and bootcode.bin are the GPU firmwares and bootloader. Their licence is described in boot/LICENCE.broadcom.
  • The kernel.img files are builds of the Linux kernel, released under the GPL (see boot/COPYING.linux)
  • The dtbs, overlays and associated README are built from Linux kernel sources, released under the GPL (see boot/COPYING.linux)
  • boot/uefi: UEFI firmware for Windows on ARM support (see UEFI README)
• extra: System.map files for the provided kernel builds (boot/COPYING.linux), and dt-blob.dts (boot/LICENCE.broadcom)
• modules: pre-built modules for kernel.img (boot/COPYING.linux)
• tools: Helper scripts for Linux and Windows
• docs: Documentation for various use cases
• drivers: Kernel modules (Linux) and Windows ARM64 drivers (experimental)
