If your Chromebook keeps turning off and back on before you can use it, Google’s supported fix is ChromeOS recovery. First disconnect accessories and restart normally if you can reach ChromeOS. If you can sign in and the loop continues, try a factory reset. If the Chromebook cannot stay on long enough to do that, enter recovery mode and reinstall ChromeOS using the internet or an erased USB drive.
This guide applies to Google’s Chromebook family. “Googlebook” is not a separate Google product; the device is almost certainly a Chromebook. Key combinations and recovery options vary by model, and recovery permanently removes local files, including Downloads.
Confirm that this is a boot loop
Google describes the symptom as a “Chromebook turns off, then back on, over and over again.” The device may show the ChromeOS logo, a recovery message, or a blank screen for a short time before restarting. A single restart after an update is different from a repeating cycle that never reaches a usable sign-in session.
Do not keep reconnecting peripherals while troubleshooting. A faulty or incompatible accessory can interfere with startup, and removing accessories is the first isolation step Google lists for hardware and system problems.

Before you erase anything
Decide whether any important files exist only on the Chromebook. Recovery permanently erases the internal drive, including downloaded files. If the machine stays on long enough to reach the desktop, copy local files to another location before using Powerwash or recovery. Files synchronized to a Google account or another service can normally be restored after setup, but a file that exists only in local storage needs its own backup.
Write down the Chromebook’s model name and any exact message shown on screen. The model is needed when creating USB media, and the wording of an error helps the manufacturer determine whether the failure is in startup, recovery media, or hardware. If the Chromebook is owned by a school or employer, confirm with the administrator before erasing it; managed enrollment may need to be restored afterward.
1. Disconnect accessories and perform a normal restart
Remove external devices
Turn off or unplug anything connected to the Chromebook: USB storage, mice, keyboards, hubs, displays, and other accessories. Leave only the Chromebook itself connected. If the loop stops, reconnect devices one at a time after ChromeOS is stable so you can identify the one that triggers the restart.

If the Chromebook remains on long enough to reach ChromeOS, use the normal power menu to shut it down, then turn it back on. Google recommends restarting before attempting a reset when a user can sign in. If the machine immediately loops again or never reaches a sign-in screen, move to recovery rather than repeatedly forcing normal restarts.
A normal restart does not reinstall or erase ChromeOS. It is simply a way to determine whether the cycle was temporary and to make sure all accessories have been removed before more destructive steps.
2. Try a factory reset only when you can sign in
Google places a factory reset, also called a Powerwash, before full recovery only when the user can sign in. Restart first, then use ChromeOS’s reset option if the problem remains. Follow the on-screen warnings and complete the reset while the Chromebook is connected to its network.
A factory reset is not a guaranteed cure for a Chromebook that cannot complete startup. If you cannot sign in, cannot keep the Settings app open, or the device restarts before the reset can finish, skip this step and enter recovery mode instead.

What a factory reset is for
- It returns the accessible ChromeOS installation to its initial state.
- It is useful when the system starts normally but software settings or the user profile appear damaged.
- It does not replace ChromeOS itself in the way recovery does.
Back up any locally stored files before resetting. Files already synchronized to a Google account or another service can normally be retrieved after setup, but local files need their own backup.

3. Enter Chromebook recovery mode
Recovery mode is the required route when the boot loop prevents a normal sign-in. The exact key combination depends on the Chromebook’s design.
Most clamshell and convertible Chromebooks
- Turn the Chromebook off if it is responding. If it is cycling too quickly, wait for the next startup screen.
- Press and hold Esc and Refresh.
- While holding those keys, press the Power button.
- Release the Power button, then release Esc and Refresh when the recovery message appears.
The Refresh key normally has a circular-arrow icon in the top row. Do not release the two recovery keys as soon as the screen goes dark; wait for the recovery prompt.
Models that use the Maximize key
Some Chromebook models use Esc plus Maximize instead of Esc plus Refresh. Maximize is the top-row key marked with a rectangle or two-corner icon. Hold Esc and Maximize, press Power, and release the keys when the recovery screen appears.

For a Chromebook tablet, hold Volume Up, Volume Down, and Power together for at least 10 seconds. Release them when the recovery screen appears. A detachable keyboard may use the tablet sequence rather than the clamshell sequence.
If the screen never appears
- Repeat the sequence with the Chromebook fully powered off.
- Use the model’s physical keys rather than an external keyboard.
- Check the manufacturer’s support documentation for that model’s key variation.
- If the device belongs to a school or employer, stop and ask the administrator before proceeding.
Google’s general instructions cannot identify a hardware fault or a model-specific variation from the symptom alone. If the documented combinations do not produce recovery mode, manufacturer support is the appropriate next step.
4. Choose internet recovery or USB recovery
Once recovery mode opens, read the options on the screen. Newer Chromebooks may offer Recover using internet connection. Older models may not support that option, and some older devices may no longer support current updates or recovery.
| Recovery route | What you need | When to choose it |
|---|---|---|
| Internet recovery | The Chromebook and a working internet connection | The recovery screen displays the internet option |
| External USB recovery | Another computer with Chrome and an erasable USB flash drive of at least 8 GB | Internet recovery is absent or unavailable |
Google does not publish comparative success rates for these methods. The meaningful choice is determined by the option your model supports and whether you have another computer and a suitable USB drive.
Internet recovery is usually the simpler route because it does not require a second computer or removable media. USB recovery is the fallback when the model has no internet option, the option is unavailable, or the Chromebook cannot complete that online path. Neither route preserves files on the Chromebook’s internal drive.

5. Use internet recovery when it is offered
- At the recovery screen, select Recover using internet connection.
- Connect to the requested network and follow each on-screen instruction.
- Allow the Chromebook to download and reinstall ChromeOS without interrupting it.
- Wait for the automatic restart that Google says occurs when the process is complete.
- Complete the initial ChromeOS setup and test several restarts before reconnecting accessories.
If the internet option is missing, the model may not support it. Do not treat its absence as evidence that the Chromebook is unrecoverable; use the external-disk method if the model supports USB recovery. If the online process stops with an error, record the exact wording and move to USB recovery when available rather than repeatedly restarting into the same loop.
6. Create and use a USB recovery drive
Prepare the second computer and USB drive
You need another Chromebook or a Windows or Mac computer with Google Chrome. You also need a USB flash drive with at least 8 GB of capacity. The drive will be erased while the recovery media is created, so copy anything important from it first and do not use a drive containing needed files.
The USB requirement is a capacity specification, not a recommendation to buy a particular brand or model. You may not need to purchase a drive at all if internet recovery works or you already have an erasable drive of sufficient capacity.

Random freezes, missing sound and display glitches usually trace back to one bad driver. Find and replace yours safely.Free scan · under a minuteCreate the recovery media
- On the working computer, install and open Google’s Chromebook Recovery Utility in Chrome.
- Choose the option to create recovery media.
- Select the affected Chromebook’s model from the list. If the utility asks for a model number, use the information printed on the Chromebook or its original documentation rather than guessing.
- Insert the USB flash drive and select it as the destination.
- Confirm the erase warning and let the utility download and write the ChromeOS recovery image.
- Eject the drive safely when the utility reports that creation is complete.
Model selection matters: recovery media is intended for the affected Chromebook model, not simply any Chromebook. If you cannot identify the model, contact the manufacturer before creating media. Choosing an approximate model can produce media that the affected device rejects, so do not substitute a different Chromebook merely because it is from the same manufacturer.
Run recovery on the affected Chromebook
- With the Chromebook at its recovery screen, insert the prepared USB drive.
- Select Recover using external disk.
- Follow the prompts to verify the media and reinstall ChromeOS.
- Do not remove the drive or interrupt the process until the Chromebook tells you it is finished.
- When the Chromebook restarts, remove the USB drive if prompted and complete setup.
Keep the recovery drive available until setup is complete. If the Chromebook returns to the recovery screen, read the message before trying the same steps again; it may indicate that the media was not recognized or that the installation failed.
Understand the data-loss consequence before recovery
Google’s official warning is explicit: “Recovery permanently erases everything on your Chromebook’s hard drive, even your downloaded files.” Recovery removes the existing ChromeOS installation and reinstalls it. This is different from simply restarting, and it is why backup belongs before recovery whenever the boot loop leaves enough time to copy files.
If the loop prevents access to the desktop, you may not be able to recover local files yourself. Files stored only in the Chromebook’s internal storage can be lost. After reinstalling, sign in with the account used on the device and restore files that were synchronized elsewhere.
Do not confuse a successful recovery with a backup operation. Recovery is intended to make the Chromebook bootable again; it is not designed to copy files off the device. Treat the erase warning as permanent even if you expect the files to be synchronized.

7. Fix common USB recovery errors
“An unexpected error has occurred”
Google’s first recommendation is to erase the recovery storage device and create the media again. Reopen Chromebook Recovery Utility, select the option to erase or recreate the recovery drive, and repeat the creation process. Make sure the drive has at least 8 GB and contains no files you need.
A second attempt fails
Try a different USB flash drive. Google notes that some drives do not work well with Chromebook recovery, even when they appear to have enough capacity. Recreate the media on the replacement drive rather than copying files manually from the first one.
The utility cannot make usable media
- Confirm that Chrome is installed on the second computer.
- Reopen the Recovery Utility and select the affected model again.
- Erase the USB drive through the utility before retrying.
- Use a different USB port or a different flash drive if the creation repeatedly stops.
If the USB drive is created successfully but the Chromebook still rejects it, verify the model selection and try another drive before assuming the Chromebook itself is defective. A drive can have enough nominal capacity and still be incompatible with the recovery process.
8. What to do when recovery does not solve the loop
If internet recovery or a correctly created USB recovery drive completes but the Chromebook continues turning off and on, the problem may be outside the software repair that recovery can address. Google’s guidance is to contact the Chromebook manufacturer when troubleshooting and recovery do not resolve the problem.
Have the model name, the exact recovery message, and the steps already attempted ready for support. Describe whether the device reaches the recovery screen, whether recovery completes, and whether the loop occurs with all accessories disconnected. Those details help the manufacturer distinguish a failed installation from a hardware problem.
Do not assume that repeating recovery indefinitely will repair a hardware fault. Once the documented internet and USB paths have been tried, manufacturer support is the appropriate escalation. Google’s general instructions do not identify a model-independent replacement part or repair procedure.

A Chromebook managed by a school or employer may have administrative controls, enrollment requirements, or restrictions on resetting and recovering it. Contact the organization’s administrator before using Powerwash or recovery. The administrator can confirm whether you are authorized to erase the device and can restore its managed configuration afterward.

For a personally owned Chromebook, the manufacturer is the escalation point after Google’s documented recovery paths fail. Google’s general support pages do not provide a model-independent hardware repair procedure.

10. Verify the Chromebook after recovery
After setup finishes, sign in and let ChromeOS reach a stable desktop before reconnecting accessories. Shut down and start the Chromebook again to confirm that it can complete more than one boot. Reconnect the mouse, storage, hub, display, or other devices one at a time; if the loop returns after one connection, disconnect that accessory and report the pattern to support.
If the device remains stable with no accessories but fails when a particular device is attached, the accessory is an important troubleshooting detail. If it loops even after a clean recovery with everything disconnected, provide that result to the manufacturer rather than recreating the same recovery media repeatedly.
Boot-loop decision checklist
- Disconnect every external accessory.
- Restart normally if ChromeOS is usable.
- If you can sign in and the loop persists, try a factory reset after backing up local files.
- If you cannot sign in, enter recovery mode with the key sequence for your form factor.
- Use internet recovery when the screen offers it.
- Otherwise create model-specific USB media with Chrome and an erasable drive of at least 8 GB.
- If USB recovery reports an unexpected error, erase the media and retry, then try another drive.
- After recovery, test several restarts before reconnecting peripherals.
- Contact the administrator for a managed device or the manufacturer when recovery still fails.
Frequently Asked Questions
Will a factory reset fix a Chromebook that never reaches the sign-in screen?
Not necessarily. Google places Powerwash before full recovery only when you can sign in. If the Chromebook cannot stay on long enough to reset, enter recovery mode instead.
Free tools Windows power users keep installed
One-click scans. No signup required.
Does Chromebook recovery erase my Downloads folder?
Yes. Google says recovery permanently erases everything on the Chromebook’s hard drive, including downloaded files. Back up local files first whenever the boot loop allows it.
How large must the USB recovery drive be?
At least 8 GB. The drive is erased while recovery media is created, so use one that contains no needed files.
Can I use any Chromebook recovery image?
No. Use Chromebook Recovery Utility on another computer with Chrome and select the affected Chromebook’s model. Media for a different model may be rejected.
What if my Chromebook has no internet recovery option?
Older models may not support internet recovery. Use the external-disk method with model-specific USB media if the model supports it.
Do these 3 things before closing this tab:

Erase the recovery drive and create the media again. If it fails again, try a different USB flash drive. Contact the manufacturer if recovery still does not work.
Who should fix a school or work Chromebook stuck in a loop?
Contact the organization’s administrator before Powerwash or recovery. Managed devices may require authorization and re-enrollment after an erase.
The Bottom Line
Remove accessories and restart if ChromeOS is usable. If you can sign in, back up local files and try Powerwash; if you cannot sign in, use recovery mode. Choose internet recovery when offered, or create model-specific USB media with Chrome and an erasable drive of at least 8 GB. Recovery permanently erases local storage. If the process fails after a clean retry and a different drive, contact the Chromebook manufacturer—or your school or workplace administrator for a managed device.
