Not everyone needs a computer with a full set of bells and whistles. A Chromebook’s simplified interface makes it popular with schools—and those of us who serve as IT support for less tech-savvy relatives. It can cost less than a budget PC, too.

You might not even need to spend anything if you have an older laptop already lying about. Installing the equivalent of Chrome OS onto aged hardware takes less than an hour’s worth of elbow grease, and the final result often feels snappier than today’s dirt-cheap Chromebooks.

Here’s how to do it.

How to convert a laptop into a Chromebook

For this project, we’ll be using Neverware’s CloudReady operating system, which is based on Chromium OS—the same open-source code that Google built Chrome OS on. You can read more about the basic differences between the two if you’re curious, but all you need to know is that Neverware has made the experience of using CloudReady all but identical to Chrome OS.

Step 1: Check that your laptop will meet the requirements

Like Chrome OS, CloudReady’s system requirements are very minimal. The laptop must have 2GB RAM, 16GB storage, full BIOS access, and ideally been manufactured after 2007. You will still need to check your CPU model, though, as Neverware says that processors with Intel Graphics Media Accelerator (GMA) 500, 600, 3600, or 3650 graphics hardware don’t meet CloudReady’s performance standards. (In other words, Atom processors from the Silverthorne, Lincroft, and Cedarview families, which were found in low-end laptops between 2008 and early 2012.)

Your best-case scenario is to find your laptop on Neverware’s list of certified devices, which clearly outlines support for features like a webcam or touchscreen. (Click on the model’s name to see those details.) We lucked out that our test model, a 2013 Lenovo ThinkPad X240, had full feature support across the board.

Note: On the compatibility list, you’ll see desktop systems like iMacs and NUCs listed as well—so if you have a spare monitor, mouse, and keyboard, you can instead spin up a Chromebox. Systems running integrated graphics work best.

If your laptop meets the hardware requirements but isn’t on the certified devices list, don’t worry. You can try out CloudReady from the flash drive you’ll create next, which will allow you to test out how well it works without having to nuke your system.

FRIENDLY REMINDER: Before you begin installing CloudReady, back up any files within your existing OS! The process is the same as a clean install of Windows, Linux, or MacOS and will completely wipe your drive.
