How to flash SD card images on a Chrome book will be explained in this article. You’re in luck if you use a Chromebook and need to flash an operating system image to an SD card. It turns out that you may flash customised operating system images using the Chrome OS recovery tool.
This tutorial will teach you how to flash customised OS images on SD cards using the official Chrome OS recovery tool. To use an SD card with Chrome OS, make sure you have an SD card reader and a suitable SD card.
Why do you need to flash an SD card image on your Chromebook?
There is no standard disc imaging tool included with Chrome OS.
Even worse, switching on Linux doesn’t fix the problem because no Linux SD card imaging apps can function and the Debian container that Chrome OS runs on is unable to access to USB devices or the internal hard drive.
Every Chromebook does, however, include a “Recovery” feature.
To flash official Chrome OS recovery images to SD cards and USB flash drives, use this utility.
But you may also flash customised images using the recovery tool.
How to create a custom SD recovery image
Start downloading the OS image to generate a customised SD recovery image.
For instance, you would manually download the OS image from the official website if you needed to flash the Lakka game OS to an SD card on your Chromebook. This is the best way of how to flash sd card images on a chromebook.
TarXZ and TarGZ are the most used formats for OS images.
Unfortunately, TarXZ or TarGZ formatted images cannot be safely flashed on Chrome OS.
As a result, you must first extract the IMG file before re-compressing it as a ZIP package.
Open the “Files” application in Chrome OS to extract your TarXZ or TarGZ file.
Locate the TarXZ or TarGZ file and do a right-click after it has opened.
After performing a right-click on the TarXZ/TarGZ file, choose “Open” from the menu.
This will mount the archive in the Chrome OS files app when you click it.
Next, transfer the IMG file from the archive to the Chrome OS files app’s “My Files” folder.
Once the IMG image has been copied to “My Files,” use the mouse to right-click on it and choose “Zip selection.”
Your IMG file will be compressed into a ZIP format that the Chrome OS recovery programme will accept by clicking “Zip selection.”
