The app creates apple partitions on a flash to boot Ubuntu

• Etcher version:

Etcher 1.3.1

• Operating system and architecture:

I use the Etcher app on MacBook (Max OS High Sierra / 10.13.3). But the flash drive I’m going to use to install Ubuntu on a Win 10 notebook (ASUS).

• Image flashed:

ubuntu-17.10.1-desktop-amd64.iso

• Do you see any meaningful error information in the DevTools?

no.

After finishing flashing, I’ve checked partitions with diskutil and here’s the output:

$ diskutil list
...
/dev/disk2 (external, physical):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:     Apple_partition_scheme                        *8.1 GB     disk2
   1:        Apple_partition_map                         4.1 KB     disk2s1
   2:                  Apple_HFS                         2.4 MB     disk2s2

Any ideas on why Ubuntu installer is partitioned this way?

Here’s what the flash drive was before flashing the image, by the way:

/dev/disk2 (external, physical):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:     FDisk_partition_scheme                        *8.1 GB     disk2
   1:                       0xEE                         8.1 GB     disk2s1

Thank you. I’ve just thought that Etcher for macOS would intentionally burn images able to boot on Apple hardware. And that it’s just me trying to make flash drive to boot later a different machine 😃

Nah, Etcher doesn’t do anything that “clever”; all it does is copy them byte-by-byte like @jhermsmeier said (much like the command-line tool dd would do).
