You will need tools like Rufus (for standard partitioning) or DISM++ / WoA Deployer (if flashing specifically to a Raspberry Pi or Lumia phone).
Modern ARM64 software targets Windows 10/11 APIs. Standard 32-bit (x86) emulation is highly unstable or non-existent in this specific build, restricting you entirely to built-in inbox applications. Conclusion
Installing Windows 8.1 on ARM64 hardware is a specialized task because Microsoft never released a consumer ARM64 version of this operating system. While standard Windows 8.1 supports x86 and x64 architectures, the ARM-specific version, known as , was only available as a 32-bit (ARMv7) OS pre-installed on specific devices like the Surface 2.

This command builds a dual-boot sector ISO file named Windows_8.1_ARM64.iso in your root workspace directory. Step 3: Target Hardware and Environment Preparation Conclusion Installing Windows 8
Since Windows 8.1 is effectively unavailable and unsupported, the practical path forward involves using or Windows 11 on ARM . These are actively maintained, have much better hardware support, and offer x86 application emulation.
