SD card not bootable

I am using etcher 1.4.8 on Ubuntu 16.04 and attempting to create a hass.io image (hassos_rpi2-1.13.img) file to an SDcard. Trying with 2 separate cards and neither are bootable. Filesystem was created ok.

Any suggestions?

Etcher only writes what’s in the image itself byte-to-byte, so the only images that are expected to (possibly) boot when flashed with Etcher are Hybrid ISOs as far as I know. You can read more on it here and possibly here

I ended up using dd and it wrote the image fine and it is bootable as expected.
