You can create a PE system using a USB flash drive. Store a software called "DiskImage" in the remaining space of the PE system, which is only 64KB by the way. After booting into the PE system, use "DiskImage" to write the unzipped Armbian image (armbian.img) into it. Note that the detail here is to write the image to "Physical Disk 0". It's an option similar to such physical disk options, not the drive letter.
