🪟 Windows

Grab balenaEtcher or Rufus, pick the ISO and your USB stick, click Flash, then boot the target machine from that USB.

🐧 Linux / macOS

Use balenaEtcher, or write it from a terminal:

sudo dd if=kilasos-1.0.0-amd64.iso of=/dev/sdX bs=4M status=progress && sync

Replace /dev/sdX with your USB device — double-check it's the right one.
