Every laptop eventually shows its age—hard drives start grinding with constant loading noises, and even basic Windows 10 animations bog down performance. If your old laptop or PC is struggling, I've found a reliable way to extend its life: transform it into a lightweight Chromebook using CloudReady, a Chromium OS distribution built specifically for this purpose.
As someone who's revived multiple aging machines this way, I can attest to how CloudReady delivers the snappy, secure experience of Chrome OS on unsupported hardware.
Important Note: Neverware, the developers of CloudReady, recommend using an 8GB or 16GB USB flash drive (though they don't specify why). For a full hard drive installation, ensure your PC is on their list of supported devices to avoid compatibility issues.

Once you've created the recovery image—a process that may take some time—eject the USB drive and insert it into the target PC. Power on while repeatedly pressing F12 (or F1, F10, or another F-key depending on your model) to access the boot menu, then select the CloudReady USB drive.

CloudReady will load shortly, prompting you to sign in with your Google account details. After setup, you'll reach the familiar CloudReady desktop.
At this point, you can run CloudReady directly from USB, or install it to the hard drive—either as the sole OS (erasing existing data) or in dual-boot mode alongside Windows.
To install, reboot without signing in. On the login screen, click the notification center in the lower-right corner, then select “Install CloudReady.” Choose your preferred setup (full replace or dual-boot) and follow the prompts.

CloudReady is an excellent Windows alternative for sluggish PCs. Personally, I boot into it for quick writing, browsing, or light tasks, reserving Windows for demanding apps like gaming or Photoshop (which aren't feasible on CloudReady). Always verify device compatibility first; if unsure, stick to USB booting.
