ChromeOS 16371.61.0
ChromeOS Flex, developed by Google, is a free and lightweight Linux distribution based on Gentoo-derived ChromeOS.

The product's functionality can be further extended by installing a Debian-based Linux subsystem with a complete Linux development environment. ChromeOS Flex is available as a BIN image that can be transferred to a bootable USB Flash drive; it can be used in a 'live' mode or it can be permanently installed to a computer's hard disk.
