Today, Mytour will guide you through the process of enabling USB boot on your Chromebook. This option becomes available only after you activate Developer Mode, a step that will erase all data on your Chromebook.
Steps
Enable Developer Mode
Back up your data on the Chromebook. Once activated, Developer Mode will delete all data and any custom changes you've made to the device.
Turn off your Chromebook. To do this, click on your account photo in the menu and select Power.
Press Esc+F3 at the same time as the power button. The Chromebook will boot up and prompt you to connect to a recovery media.
- Some models may require inserting a paperclip or a pointed object into a small hole on the side of the device while pressing the power button. If you find a small hole on the side of the body labeled 'Recovery,' try this method.
Press Ctrl+D on the 'Insert recovery media' screen. A confirmation message will appear.
Press ↵ Enter to confirm. Your Chromebook will reboot. Once the transition is complete, you'll see the message 'OS verification is OFF.' From now on, you'll see this screen every time the Chromebook starts up.
Enable boot from USB
Press Ctrl+Alt+F2 on the main screen. A control panel window with a black background and white text will appear.
Type sudo crossystem dev_boot_usb=1 into the command prompt.
Press ↵ Enter. The command will execute.
Plug in the USB drive you wish to use as a boot device. Once USB booting is enabled, you can use the control panel window and reboot the system from this drive.
Press Ctrl+U on the "OS verification" screen. The Chromebook will reboot from the connected drive.
