Since NayuOS is still based on Chromium OS you should only need dev mode enabled to run it. It&#x27;ll boot the same way that Chromium OS does. Legacy boot is only necessary for a traditional Linux distro that isn&#x27;t using the Chrome OS format for kernel images.<p>For the record, the write protect is just a screw on Chrome OS devices and doesn&#x27;t need to be desoldered.
