You seem to be getting a bit farther than I have. I am trying to boot a Mint 19 USB stick but never get close to loading it.
I have not yet set up Windows 10 as I know nothing about that O/S and don’t want to use it in any case. When I power on the Ubook I am taken to the Windows set up. I get the voice prompting me to set up wifi, choose a name and password, etc.
Unlike other computers this Ubook just ignores the USB stick inserted into it and goes straight to Windows set up. At that point I am forced to press the power button for about five-six seconds until the Ubook shuts off. Unlike the previous poster my Ubook does not get to the point that it shuts itself off when it detects Linux.
I do not know what to do at this point. I really do not want to go through the Windows set up and configuration, but if that’s necessary I guess I’ll bite the bullet. But given all the recent news about Windows 10 security problems I’d really rather not have to deal with that O/S at all.
Thanks to anyone who can get this Ubook up and running with a “live” version so I can see how (if??) it will work with Linux.
