You can give a compatible Windows PC a Chromebook-like setup for free by installing ChromeOS Flex. It brings many ChromeOS features, but the result is a PC running ChromeOS Flex—not a Chromebook with identical hardware or every Chromebook feature. First check Google’s certified-model list for your exact PC, then decide whether to try Flex from a USB drive or install it.
What you’ll install—and what you won’t get
ChromeOS Flex is Google’s free way to replace an existing Windows or Mac operating system with a ChromeOS-based system. Google describes it as offering almost all the benefits of ChromeOS, but important differences remain: ChromeOS devices have Google-designed security chips and firmware integration that Flex PCs lack, and managed Google Play apps are available only on ChromeOS devices. Some PC features, including Bluetooth, touchscreens, SD card readers, and brightness or volume keys, may also be unsupported on a particular model.
There is one main free conversion route in Google’s official guidance: ChromeOS Flex. You can first run it from its USB installer, or install it on the PC if the trial works for your needs.
Check whether your PC is a good candidate
Find the exact model on Google’s list
Look up the manufacturer and exact model number in Google’s ChromeOS Flex certified-model list. Google tests individual models, so a similar-looking variant may behave differently. Review the model notes and its certification end date. Google guarantees a core set of functions on certified models, including installation, keyboard, USB, system graphics, network where present, and audio input and output; not every feature is guaranteed.

- Intel Celeron N4120: 4 Cores & Threads, 1.1GHz Base Clock, Up to 2.6GHz Boost Clock, 4MB Cache, Intel UHD Graphics 600. The perfect combination of performance, power consumption, and value helps your device handle multitasking smoothly and reliably with four processing cores to divide up the work.
Non-certified models may work, but Google does not guarantee their stability, functionality, or performance across regular updates. They are also ineligible for Chrome Education or Chrome Enterprise support. When a model’s certification period ends, testing and Google support cease, and fixes or future updates are not guaranteed.
Confirm the hardware minimums
Google’s minimum requirements are an Intel or AMD x86-64-compatible device, at least 4 GB of RAM, at least 16 GB of internal storage, the ability to boot from USB, and full administrator access to BIOS. Google says Intel or AMD processors from 2012 or earlier and Nvidia graphics from 2014 or earlier are not recommended or supported and are unlikely to work.

- Storage: 16GB Flash Memory
- OS: Chrome OS
- Screen Size: 11.6"
Model certification and minimum requirements answer different questions: the requirements are a baseline, while the certified list is where Google identifies models it has tested and supports. Even a certified PC can have individual features that are unsupported or untested.
Prepare the installer and protect your files
You need a separate ChromeOS, Windows, or Mac computer with the current Chrome browser to create the installer using Chromebook Recovery Utility. That computer can be different from the old PC you plan to convert. Google also documents other ways to create installation media that do not require Chrome in its installation guide.

- Intel Processor Up to 2.80GHz, 4GB DDR4, 128GB Storage
- 15" FHD IPS Display, Intel UHD Graphics
- 1x USB Type C, 1 x USB Type A, 1x Headphone/Microphone Combo Jack, HDMI
- Fast WiFi and Bluetooth, Integrated Webcam
- Chrome OS, AC Charger Included, Pastel Silver
- Use a USB drive with at least 8 GB of capacity. Some SanDisk and other drives may not work.
- Creating the installer erases everything on that USB drive, so copy off any files you want to keep.
- Back up important files from the Windows PC before installation. Read the on-screen installation prompts carefully before choosing to install, and keep the backup until you have confirmed your files and setup are in order.
Google’s high-level preparation instructions establish that the USB installer is erased during creation; they do not specify in the cited preparation information whether the target PC’s internal drive is wiped during installation. Do not treat installation as reversible or choose an install option until you understand the prompt and have protected your data.
Make a ChromeOS Flex USB installer
- On the separate computer, open the current Chrome browser and install or open Chromebook Recovery Utility.
- In Recovery Utility, choose the option to create a recovery drive, then select Google ChromeOS Flex when asked to identify the Chromebook. Follow the utility’s prompts to write the installer to an 8 GB-or-larger USB drive. Google’s ChromeOS Flex page describes this USB creation process.
- Wait for the utility to finish, then safely remove the USB drive. Its previous contents have been erased.
Boot the old PC and choose a trial or installation
- Insert the USB installer into the target PC and restart it.
- Open the PC’s boot menu during startup, or enter BIOS/UEFI settings, and select the USB drive. The key or menu varies by manufacturer; use the PC maker’s instructions if you are unsure.
- When ChromeOS Flex starts, use the available option to run it temporarily from the USB drive if you want to check it before installing. Confirm that essential hardware—such as Wi-Fi, sound, keyboard, and any features you rely on—works for you.
- If you decide to proceed, follow the on-screen installation prompts. Review each prompt before confirming any changes to the PC’s internal storage, then complete setup.
Google outlines the process as creating the USB, booting from it, choosing to run Flex temporarily or install it, and setting up the device. The temporary run is the lower-commitment way to check a non-certified or unfamiliar model, but it cannot guarantee that every feature will work after installation or through later updates.

Fix common USB boot and startup problems
The PC does not start from the USB drive
- Try a different USB port, including USB 2, USB 3, or USB-C if available.
- Try a different USB drive; some models may not work as installer media.
- Check BIOS/UEFI to ensure USB boot is enabled and that the USB drive is first in the boot order.
The install appears successful, but startup shows a black screen or no operating system
Google’s ChromeOS Flex troubleshooting guidance recommends resetting BIOS defaults, trying UEFI boot (or Legacy if UEFI fails), checking for an EFI boot file, and updating the BIOS from the PC manufacturer if an update is available. BIOS labels and procedures vary by manufacturer, so use its documentation before changing firmware settings.

ChromeOS Flex is a reasonable free option if your exact PC is certified, its required hardware functions are supported, and a browser-focused ChromeOS experience meets your needs. Keep the original operating system or choose another solution if you depend on managed Google Play apps, Chromebook-specific security hardware, or a model feature that does not work reliably. Google’s sources do not establish a general success rate for conversions or a guaranteed speed improvement for old PCs, so compatibility and performance should be evaluated on the specific machine.
