ReactOS is an open-source operating system designed to be binary compatible with Windows applications and drivers. It consists of a low-level system kernel that manages hardware resources and a binary compatibility layer that enables the execution of software designed for the Windows binary interface.
The project implements a cross-platform build system and toolchain for compiling and deploying bootable operating system images across different hardware architectures. This includes the use of cross-compilation toolchains and a hardware-abstraction layer to support various processor and motherboard types.
The system covers the generation of bootable ISO images and media for installation on physical or virtual hardware. It includes capabilities for formatting system partitions and deploying the operating system to supported file system types.
