See https://github.com/balena-io/etcher/issues?q=is%3Aissue+chromebook and https://github.com/raspberrypi/rpi-imager/issues/92

From what I can tell (I don't have a Chromebook myself), ChromeOS only gives Linux "high level access" to the USB devices, and doesn't allow the "low level access" needed by tools like Etcher (needed to write to the disk at a block-level instead of the filesystem-level).

Many thanks lurch for that. It seems pretty terminal then (excuse the pun).

Just to be clear : does anyone have experience of flashing an SD card with chromiumOS for a pi4B from a ChromeBook or PixelBook? Or as lurch says, is it impossible?
