Chrome OS is definitely picking up stream and so is the Chromebook.Just like with Windows and Mac, you can create a recovery flash drive or on a SD card.
Windows, Linux, and OS X allow you to create recovery drives that you can use to get your system back in case something goes awry. Another operating system that’s picking up steam is Chrome OS on the Chromebook. Just like with Windows, you can create a Chrome OS recovery flash drive.
If you receive a new Chromebook it’s important to create a system recovery image in case something goes wrong and a Hard Reset or Power Wash (resetting it to factory settings) doesn’t work.
Create Chromebook Recovery Drive
Grab a USB flash drive or SD card that’s 4GB or higher and insert it into one of the open USB slots. Then open the Chrome browser and type: chrome://imageburner into the address bar to get the following screen.
Update 5/28/2019: Google has removed the tool from your Chromebook. Instead, download the Chromebook Recovery Utility from Google.
Select the drive you popped in to the Chromebook and wait for the recovery image to download.
Select the drive you popped in to the Chromebook and wait for the recovery image to download and the recovery drive is created.
That’s it! Provided everything went the way it should, you’ll see the following successful message. Take out the flash or SD card and keep it in a safe place in case you need it at some point.
Recover Your Chromebook
If you’re at the point where you receive an error message saying “Chrome OS is missing or damaged” and haven’t created a recovery drive yet, you still can. You’ll need either a Windows, Mac, or Linux computer and a flash or SD drive that’s at least 4GB in size. You can find the instructions and correct download from this Google Page.
You’ll need to download and run the system, and enter the model number of the device with appears at the bottom of the error. Then follow the on-screen instructions.
Bonus Chromebook Tip:
If you want to create a recovery drive using your Windows or Mac computer, before getting an error message, you need to find the correct model to enter in the screen above. To do so, type: chrome://system and expand the section called HWID. There you’ll find it – in my example for the Samsung Chromebook 303 it’s SNOW DENALI A-E 2577.
To boot from the USB drive, typically you’ll need to hold down the Power+Escape+Refresh then go through the recovery. Then some have a hidden recovery button where you need to stick a paperclip in – either on the bottom or next to a USB port.
Basically the only time you’ll need to recover your Chromebook is if you’re messing around in developer mode, but you never know. Making sure to have your recovery drive handy and ready to go, gives you peace of mind, and it’s easy to create.
