Check Compatibility First

Google maintains an official list of certified devices. Visit chromeos.google/os/chromeosflex/devices/ to check your specific model. Most Intel-based laptops and desktops from 2012–2020 are fully supported.

⚠️ Note: ARM processors (Qualcomm Snapdragon on some Surface devices) are NOT supported by Chrome OS Flex. You need x86-64 hardware.

Step 1: Create Chrome OS Flex USB Installer

You need a USB drive (8 GB+) and another computer to create the installer. Use Google's official Chromebook Recovery Utility extension for Chrome browser:

1
Install Chromebook Recovery Utility from the Chrome Web Store on any Chrome browser. Search "Chromebook Recovery Utility" or visit the Chrome extensions page.
2
Insert your USB drive (8 GB+). Open the Recovery Utility, click the gear icon → "Use a local image" — or select "Select a model from a list".
3
In the device search, type "Flex" and select Google ChromeOS Flex → ChromeOS Flex. Click Continue.
4
Select your USB drive and click Create now. The tool downloads Chrome OS Flex (~1 GB) and writes it to the USB. Takes about 10–15 minutes.
5
Boot your old PC from the USB by pressing F12 (or F2/DEL depending on manufacturer) during startup to access the boot menu.

Try Before You Install

Chrome OS Flex lets you run directly from USB without installing. Boot from USB and test that your hardware is fully compatible — Wi-Fi, keyboard, trackpad — before committing to installation. If everything works, click "Install ChromeOS Flex" from the USB session.

Step 2: Enable Linux (Crostini) Environment

Chrome OS Flex includes a full Debian Linux environment called Crostini. This is where OpenClaw runs. Enable it in settings:

1
Click the system clock in the bottom-right corner → click the gear icon to open Settings.
2
Scroll down to "Advanced" → "Developers" → click "Linux development environment".
3
Click "Turn On". Choose your username and disk size. Allocate at least 10 GB for OpenClaw and its data. Click Install.
4
Wait 5–10 minutes for Debian to download and set up. A Terminal window opens automatically when complete.

Verify Linux is Working

In the Linux terminal, run:

cat /etc/os-release
uname -r

You should see Debian GNU/Linux 11 (Bullseye) or 12 (Bookworm) and a Linux kernel version. You're ready to proceed.

Step 3: Install Node.js 22+ on Crostini

OpenClaw requires Node.js 22 or newer. The default Debian repo has an older version, so use NodeSource's installer:

Recommended: NodeSource Official Script

# Update package lists first
sudo apt update && sudo apt upgrade -y

# Install curl if not present
sudo apt install -y curl

# Add NodeSource repository for Node.js 22 LTS
curl -fsSL https://deb.nodesource.com/setup_22.x | sudo -E bash -

# Install Node.js
sudo apt install -y nodejs

# Verify installation
node --version    # Should show v22.x.x
npm --version     # Should show 10.x.x

This installs both Node.js and npm in a single command. The NodeSource script automatically configures the correct repository for Debian.

Alternative: NVM (Node Version Manager)

NVM lets you easily switch between Node.js versions — useful if you run multiple projects:

# Install NVM
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash

# Reload shell
source ~/.bashrc

# Install Node.js 22
nvm install 22
nvm use 22
nvm alias default 22

# Verify
node --version

Step 4: Install OpenClaw

With Node.js ready, install OpenClaw using the quick npm method:

Method 1: Quick Install (Recommended)

# Install OpenClaw globally
npm install -g openclaw@latest

# Initialize a new agent
openclaw onboard --install-daemon

# Or create a named project folder
mkdir ~/my-openclaw && cd ~/my-openclaw
npx openclaw init .

Method 2: One-Line Installer Script

# Official installer (downloads and configures automatically)
curl -fsSL https://openclaw.ai/install.sh | bash

This script handles Node.js version checking, installs OpenClaw, and runs the initial onboarding wizard automatically.

Method 3: Clone from GitHub (Developer)

sudo apt install -y git
git clone https://github.com/openclaw/openclaw.git ~/openclaw
cd ~/openclaw
npm install
npm run setup

Setup Wizard Walkthrough

Q1AI Provider: Select Anthropic Claude (recommended) or OpenAI. Both work perfectly on Crostini.

Q2API Key: Paste your Anthropic or OpenAI API key. Get one from anthropic.com or platform.openai.com.

Q3Messaging: Choose Telegram (easiest for remote access), Discord, or WhatsApp.

Q4Persistent Memory: Enable this — it's one of OpenClaw's most powerful features, giving your agent long-term context.

Step 5: Run OpenClaw as a Background Service

To keep OpenClaw running 24/7 on your Chrome OS Flex machine — even when the terminal is closed — use systemd or PM2:

Option A: systemd Service (Recommended)

Create a systemd service so OpenClaw starts automatically:

# Create the service file
sudo nano /etc/systemd/system/openclaw.service

Paste this content (replace youruser with your Linux username):

[Unit]
Description=OpenClaw AI Agent
After=network.target

[Service]
Type=simple
User=youruser
WorkingDirectory=/home/youruser/my-openclaw
ExecStart=/usr/bin/node /home/youruser/my-openclaw/index.js
Restart=always
RestartSec=10
Environment=NODE_ENV=production

[Install]
WantedBy=multi-user.target

# Enable and start the service
sudo systemctl daemon-reload
sudo systemctl enable openclaw
sudo systemctl start openclaw

# Check status
sudo systemctl status openclaw

# View logs
journalctl -u openclaw -f

Option B: PM2 Process Manager

npm install -g pm2
cd ~/my-openclaw
pm2 start npm --name "openclaw" -- start
pm2 startup    # Follow the printed command to enable autostart
pm2 save

Chrome OS Flex Specific Tips & Optimizations

Prevent Sleep When Lid is Closed

By default, Chrome OS sleeps when you close the lid — bad for a 24/7 server. Fix this in Settings → Power → change "When idle: sleep while charging" to "Keep display on". For lid close behavior, go to Settings → Device → Power → When device is idle or lid is closed → set to "Keep awake".

Expand Linux Disk Size

If you allocated less space initially, you can expand it: Settings → Advanced → Developers → Linux development environment → Disk size → click Change. Increase to 20–30 GB if your SSD has room.

Network Stability for API Calls

OpenClaw makes frequent API calls to AI providers. Unstable Wi-Fi causes timeouts and degraded performance. For best results: (1) Use Ethernet if possible, (2) Connect via VPN07's 1000Mbps dedicated channels for optimized routing to OpenAI and Anthropic endpoints across 70+ countries. Many Chrome OS Flex users report that connecting through VPN07 reduces API timeout errors by over 90%.

Share Files Between Chrome OS and Linux

To access your OpenClaw data and logs from the Chrome OS Files app: right-click the Linux penguin icon in the Files app shelf → "Share folder with Linux". This lets you easily copy configs and view logs without using the terminal.

Common Chrome OS Flex Issues & Fixes

"Linux container not starting"

Cause: Crostini failed to initialize, often due to low disk space.

Fix: Go to Settings → Storage Management → ensure at least 5 GB free. Then re-enable Linux from Developer settings.

OpenClaw stops after screen sleep

Cause: Chrome OS Flex suspends the Linux container when the system sleeps.

Fix: Use systemd auto-restart (RestartSec=10 in the service file). Also disable sleep: Settings → Power → Sleep when idle → Never.

API connection timeouts / slow responses

Cause: ISP throttling, geographic routing issues, or unstable Wi-Fi.

Fix: Connect VPN07 on your router (covers all devices including Chrome OS Flex). VPN07's 1000Mbps channels are optimized for AI API providers — most timeout issues resolve immediately.

"npm EACCES permission denied"

Cause: Trying to install npm packages globally without correct permissions.

Fix: Use NVM instead of system Node.js, or configure npm prefix: mkdir ~/.npm-global && npm config set prefix '~/.npm-global' echo 'export PATH=~/.npm-global/bin:$PATH' >> ~/.bashrc && source ~/.bashrc

Keeping OpenClaw Updated on Chrome OS Flex

Chrome OS Flex updates automatically in the background. For OpenClaw updates inside the Linux container, use these maintenance commands:

# Update OpenClaw to latest version
npm update -g openclaw

# Or if installed via git clone:
cd ~/my-openclaw
git pull origin main
npm install
sudo systemctl restart openclaw

# Update all Debian packages in Crostini
sudo apt update && sudo apt upgrade -y

OpenClaw typically releases updates weekly with new features, bug fixes, and new built-in skills. The entire update process takes under 2 minutes on Chrome OS Flex.

What to Do with Your Old PC After Setup

Once Chrome OS Flex is running smoothly as your OpenClaw host, here are productive ways to use the same machine:

→Network-attached storage: Share files from your old PC across your home network via Samba running in the Linux container alongside OpenClaw
→Home automation hub: Install Home Assistant in the Linux container — OpenClaw and Home Assistant make a powerful pair, with OpenClaw as the natural language interface to your smart home
→Local LLM server: Install Ollama for ARM/x86 in the Linux container to run smaller local models (Llama 3.2:3b, Phi-3.5) — reducing cloud API costs for routine tasks

Connecting OpenClaw to the Outside World

If you want your Chrome OS Flex OpenClaw agent to receive webhooks (from GitHub, Zapier, or other services), you'll need to expose it. Two safe options:

Option 1: Cloudflare Tunnel (Recommended)

Free, no port forwarding needed. Run cloudflared tunnel in Crostini to create a secure HTTPS endpoint for your OpenClaw webhooks.

Option 2: Tailscale VPN

Use Tailscale to access your Chrome OS Flex OpenClaw from anywhere — connect via VPN07 on your phone to your home Tailscale network for secure remote access.

Energy Efficiency: The Real Cost Savings

A 2013-era laptop typically consumes 15–30 watts when running Windows 10 at idle. Chrome OS Flex with Crostini running OpenClaw consumes just 6–12 watts at idle — roughly half. Running 24/7 at 10 watts:

87.6 kWh

Per year electricity

~$13/year

Electricity cost (US avg)

Compare this to a cloud VPS ($72-120/year) — running OpenClaw on your repurposed Chrome OS Flex machine saves $60-100/year in server costs alone.
