I just bought a new Remix Mini PC that I had planned on hacking and installing Ubuntu 16.04 (or the whatever the latest stable version is). It works just like any other Android except it has two USB ports and connects via HDMI to a display (see above link). It doesn't have volume rockers to get to the recovery menu but it can still go to the recovery menu if you hold down F2 on boot. Due to the fact that it doesn't have a touch screen, I just want to install the normal PC version of Ubuntu from my bootable USB Flash drive. Does anyone know of a possible way to boot from the USB drive? If so, is there a specific way I need to install Ubuntu? Could I get extra drivers, and if so, how many might I need to get everything working (HDMI, Sound, Wifi, Bluetooth, ect.)? And lastly, if I had to install Ubuntu touch, could I still get the same apps and Unity like the desktop version? The system only has 16 gigabytes of space, so I'm still wondering if it would be worth it. Thanks!
Seems you cannot install Ubuntu Desktop because the processor is based on ARM architecture and Ubuntu Desktop is meant for x86 processors.
You should probably try to install the Ubuntu ARM version meant for Raspberry Pi. Please refer this wiki for the process.
Basically, it seems to give you the server edition and then you can install packages that give you the Desktop Environment. See the extract below from the wiki.
This is a small ubuntu-server image. If you want a full desktop, go ahead and do so:
$ sudo apt-get install xubuntu-desktop # or $ sudo apt-get install lubuntu-desktop # or $ sudo apt-get install kubuntu-desktop # etc
Ubuntu (Unity) and Ubuntu-GNOME just display a blank screen, presumably because they require 3D compositing. Kubuntu works but is slow unless you turn off desktop effects under System Settings. Xubuntu and Lubuntu work fine out of the box.
