Step 1 ‐ install BalenaEtcher.
FWIW, perhaps you should reconsider if you should even use balenaEtcher.
I never figured out step 1. It’s not in the software store.
Unfortunately, this does happen at times. Therefore, it's a good idea to be aware of alternatives. One such example would be Fedora Media Writer that you may install as a flatpak. Though, the most popular is probably Ventoy.
Eventually I found an APPimg file, and it installed Balena Etcher. But it wouldn’t launch after being installed.
Unfortunately, AppImages aren't as reliable as one might expect. Assuming that your distro supports it OOTB, you're still often required to explicitly allow it to be run as an executable. Which is a good thing for the sake of secure defaults*. Granting it is simply done by:
- Right-clicking the AppImage you wish to execute
- Go into "Properties"
- Turn the switch ON that's found to the right of "Executable as Program"
You can put multiple ISOs on it, and choose at boot.
FWIW, the aforementioned Ventoy does just that.
For some reason, I was under the impression that laptops in the MNT Reform series were the only laptops that were manufactured using open (source) hardware only. Or, if there were others, that it must have been doing something so special that they deserved to be put on a pedestal. But, currently, I don't feel confident enough to state why it would be superior over say the Olimex TERES-I or Pinebook Pro.
We definitely pay a premium, but I don't know exactly why. Especially when the aforementioned Olimex TERES-I and Pinebook Pro are almost an order of magnitude cheaper.
From what I understood, Rockchip offers (at least some of) its SoCs as open source hardware. So, what MNT Reform did for the SoC is order them as open source hardware and include/publicize/provide all the schematics (etc).
FWIW, the open source hardware aspect is what I was intrigued by*.
