ReactOS has merged its Live and Boot ISOs into a single installation image, simplifying the installation process for users. This integration allows users to test the OS in a live environment and transition to installation without needing multiple discs or USB drives. The installation process still resembles older Windows versions with a text-based setup, but a full graphical installation interface is expected in the upcoming 0.4.16 build. Additionally, ReactOS is expanding its hardware compatibility with a new ATA storage driver, enabling it to boot on a wider range of storage devices. ReactOS is currently in its alpha stage of development and is not yet suitable for everyday use.
