Rufus is the preferred tool for turning the downloaded .bin.zip into a bootable USB entirely offline. Plug your USB flash drive into your Windows computer.

When you write the 64-bit .bin file to a USB drive, it creates a bootable offline installer capable of running or installing ChromeOS Flex without an active internet connection during the initial storage wipe.
