Yesterday, Google announced a new version of its Chrome OS, dubbed Chrome OS Flex, which is now available as part of the early access system. This new operating system is designed to run on older PCs and Macs.
Users confirm that it has also breathed life into older Chromebooks that have expired auto-update (AUE) or end-of-life (EOL). There are reports that the operating system works well on the Acer C720, Asus Chromebox CN60, and older HP and Lenovo Chromebooks.
Installing Chrome OS on these devices involves disabling Chrome OS firmware write protection, which ensures the device is not hacked before use. These instructions vary by device. You may also need to flash custom firmware. In short, installation is not as easy as it is on a Mac or PC.
In addition, Google officially recommends not using Chrome OS Flex on computers that have reached AUE/EOL. The company acknowledges that the system may work but will not be supported.
Google does not support installing Chrome OS Flex on expired Chrome OS devices. While you can install Chrome OS Flex on Intel or AMD x86 devices running Chrome OS, we do not support devices that have expired AUE. You may experience issues with firmware and hardware compatibility, installation, and updates.
The Google FAQ also explains that OS dual boot is not supported. The company offers to run Chrome OS Flex via a USB installer, although the live download capability is memory limited and is for "temporary study or testing" only.
