ReactOS achieves historic milestone: ARM64 port successfully boots for the first time

After 8 months of development, contributor Ahmed Arif (@sidihmeed) successfully booted the first ARM64 port of ReactOS, marking this open-source Windows-compatible OS’s official entry into the ARM architecture realm.

Technical Requirements

  • UEFI-compatible ARM64 hardware is required
  • A GICv2 or GICv3 interrupt controller must be enabled
  • Support for ARMv8-A and later architectures is necessary
  • Raspberry Pi 5 (RPI5) is supported as a special exception, since it uses a separate interrupt chip

Currently, this port remains in the experimental phase. The build code has been made public, and the developer will provide detailed compilation instructions later on.
