**How to enable USB boot on Chromebook?**

Chromebooks are known for their simplicity and security, but sometimes you may need to boot from a USB device for various reasons. Whether you want to install a new operating system or run diagnostic tools, enabling USB boot on your Chromebook is a straightforward process. Here’s a step-by-step guide to help you do it.

1. **Make sure your Chromebook is in developer mode:** Before you can enable USB boot, you need to put your Chromebook into developer mode. Keep in mind that switching to developer mode may erase all your data, so make sure to back up any important files before proceeding.

2. **Turn off your Chromebook:** To start the process, turn off your Chromebook completely.

3. **Enter recovery mode:** To enter recovery mode, press and hold the Esc and Refresh keys simultaneously, and then press the Power button. Release all three buttons once you see a recovery screen.

4. **Access the command prompt:** On the recovery screen, press Ctrl + D to access the command prompt.

5. **Enable USB boot:** Once you’re in the command prompt, type “shell” and press Enter to access the Chrome OS shell.

6. **Run a command to enable USB boot:** In the Chrome OS shell, type the following command: “sudo crossystem dev_boot_usb=1” and press Enter. This command enables USB boot on your Chromebook.

7. **Restart your Chromebook:** After running the command, you can now restart your Chromebook by typing “sudo reboot” and pressing Enter.

8. **Confirm USB boot is enabled:** Once your Chromebook reboots, press and hold the Esc key while it starts up. This will open the boot menu. If you see an option labeled “USB Storage” or something similar, it means USB boot is enabled.

9. **Connect your USB device:** To boot from a USB device, insert it into one of the USB ports on your Chromebook.

10. **Select the USB device:** Use the arrow keys on your keyboard to highlight the “USB Storage” option in the boot menu, and press Enter to select it.

11. **Follow on-screen instructions:** The bootable USB device should now take over, and you can proceed with installing an operating system or running the desired tools.

12. **Disable USB boot (optional):** If you want to disable USB boot in the future, you can follow the same steps above, but instead of enabling it, use the command “sudo crossystem dev_boot_usb=0”.
