ChromeOS Flex ISO Download: 2 Methods for Downloading ChromeOS Flex

ChromeOS Flex is Google's fast, secure, cloud-first operating system for PCs and Macs. Designed to breathe new life into older hardware, it gives your team a modern work experience without requiring new device purchases — and when you work with a certified Google partner, you'll have expert support every step of the way.

In this guide, we walk you through what ChromeOS Flex is, what your devices need to run it, and exactly how to download and install it.

What Is ChromeOS Flex?

ChromeOS Flex is a free, cloud-first operating system from Google that replaces Windows or macOS on existing Intel or AMD hardware. It shares nearly all the benefits of ChromeOS — the OS powering Chromebooks — without requiring purpose-built Google hardware.

Originally derived from Neverware's CloudReady (acquired by Google in 2020), ChromeOS Flex officially launched in July 2022 and is continuously updated. The current stable release is M-142. Updates roll out automatically in the background roughly every four weeks, so your fleet stays current with zero user disruption.

ChromeOS Flex System Requirements

Before you download ChromeOS Flex, confirm that your target devices meet Google's minimum hardware requirements. ChromeOS Flex supports most Intel and AMD x86-64 machines — including devices manufactured over the past decade.

How to Download ChromeOS Flex

There are two ways to get ChromeOS Flex onto a device: the trial (live boot) method and the full installation method using an ISO file. Google recommends the full install for production use — live boot has performance and storage limitations and does not support automatic updates or device enrollment.

Method 1: The Trial (Live Boot) Method

Live boot lets you run ChromeOS Flex directly from a USB drive without touching your device's existing OS or data. It's a risk-free way to evaluate the experience before committing to a full install.

1. Start your device using the USB installer.
2. On the welcome screen, click Get Started.
3. Select Try it first.
4. Sign in to explore the features.

Method 2: Full Installation via ISO (Recommended)

This is the path for a real, managed deployment. You'll create a bootable USB installer using the Chromebook Recovery Utility, then use it to install ChromeOS Flex on any target device.

Step 1 — Create the USB Installer

1. On a Windows, Mac, or ChromeOS device, open the Chrome Web Store and install the Chromebook Recovery Utility extension.
2. Launch the extension and click Get Started.
3. Click Select a model from a list. Choose Google ChromeOS Flex for both manufacturer and product.
4. Insert your 8 GB+ USB drive when prompted, then click Create now.
5. When the utility confirms your recovery media is ready, safely eject the USB drive.

How to Install ChromeOS Flex

With your USB installer in hand, you're ready to install ChromeOS Flex on any compatible target device.

1. Shut down the target device completely.
2. Insert the ChromeOS Flex USB installer into an available USB port.
3. Power the device on and press your boot interrupt key (often F12, Esc, or Del — check your manufacturer's documentation).
4. Select the USB drive as the boot device.
5. Choose Install ChromeOS Flex. This will erase all data on the internal drive.
6. Follow the setup prompts and enroll the device in the Google Admin console.
