Find the Chromebook Recovery Utility on the list and click on it to launch. Click on it and a drop-down list of extensions will appear. Go to the Chrome browser's extensions menu located at the top right of the Chrome browser window (it looks like a tiny puzzle piece).This is what you'll use to build the USB/SD card installer. Open a Chrome browser window on a ChromeOS, Windows PC or Mac device and add the Chromebook Recovery Utility extension via the Chrome web store.Once you've got everything needed, it's time to create the USB installer. To run ChromeOS Flex, the target laptop (or desktop) will need to be Intel or AMD x86-64-bit compatible (newer than 2010 for the best experience), have 4GB RAM or more, have at least 16GB of storage and you'll need full administrator access to the BIOS. The thumb drive will also be completely erased when creating the installer. This will be used to create the ChromeOS Flex USB installer and it doesn't need to be the same device you plan to install it on.

You'll also need a ChromeOS, Windows PC or Mac device with the current version of the Chrome browser installed. Any important files should be backed up first. Note that installing ChromeOS Flex will completely erase your entire hard drive.
