Later on I tried Google's recovery tool using this site ' ' and added that extension into chrome. Please remove all connected devices and start recovery". Used this website to install the Gallium OS through ISO USB install: Ĭhromebook rebooted and I saw the screen where it was written "Chrome OS is missing or damaged. Now on startup, pressed Ctrl+L, got the BIOS screen instead of Chrome OS. Powered off the Chromebook by typing in 'sudo poweroff' Pressed Ctrl+Alt+F2 at the Chrome OS login screen.Īt the terminal prompt, type: sudo crossystem dev_boot_usb=1 dev_boot_legacy=1 Pressed Ctrl+D at the initial startup screen to load Chrome OS. I tried ESC+Refresh+Power key to Enable Developer Mode then I pressed CTRL+D then pressed Enter to turn off the OS verification.

I removed the Write Protected Screw from the back of the Chromebook.
