These instructions will allow you to create a USB stick which can be used to reformat one or more computers with Endless OS. Compared to a normal Endless OS USB stick, a USB stick created following these instructions requires fewer clicks to reformat a computer with Endless OS, but cannot be used to try Endless OS from the USB stick, or install dual-boot with Windows.
One key advantage of the Reformatter USB is that it has an exFAT partition where the target OS image is stored. You can quickly and easily switch out the target OS image for a new one, just by replacing the original files, and you can even add more images to this partition (you'll be presented with the choice of which one to install).
Note: These instructions are aimed at special circumstances sometimes encountered by Endless partners. Most users should instead follow the simpler instructions around creating an Endless USB Stick. Please see our Installation documentation for more info.
sudo eos-write-installer --os-image /path/to/eos*.img.gz --installer /path/to/eosinstaller*.img.xz /dev/sdb
You will need Windows 7 or later to follow these instructions.
