I wrote up how to make a windows 10 USB installer from linux for quine
@iliana@cybre.space
But does that require downloading 80MBs of js+css to do it (and take ~20% longer to boot)?

@iliana@cybre.space Speaking of, the way to create a ChromeOS recovery usb is to install a chrome extension and flash to your usb drive from a browser tab.
It doesn't work on linux.
