    it should say something like chronos local host$
    type in cd ~/Downloads
    then type sudo su
    then type dd if=(whatever the downloaded iso file is) of=/dev/target
    as an example
    dd if=ubuntu-16.04.1-desktop-amd64.iso of=/dev/target
    yes make sure that u type in the iso file right after the = sign
    and once thats done eject your usb and reject and you should have a bootable usb with either linux 16.04 lts or whatever version or windows whatever verison

    a lot of people have asked about this but nobody has wired up an implementation so far. you'll have to deal with offset ranges in the source file. but with some work you'll have it under control.

    @RajVasikarla_twitter
    Great, this is an amazing feature
    thanks a lot
    do you have any pointers/references to others already implementing it?
    that could be a good start for me
    Paul Irish
    @paulirish

    you can also check out https://github.com/ChromeDevTools/devtools-frontend/blob/master/front_end/coverage/CoverageModel.js which is the underlying impl for devtools. it consumes takePreciseCoverage for JS very directly

        await new Promise((resolve) => setTimeout(resolve, 10000));
        let result = await client.send("Profiler.takePrecisionCoverage");
        fs.writeFileSync("coverage.json", JSON.stringify(result, null, 2));
