The Z83-4 is a powerful, fanless and cheap mini pc, with USB 3.0 and a very low power consumption (specifications here: http://minix.com.hk/uploads/im…EO_Z83-4_-_Spec_Sheet.jpg)
You cannot boot the Z83-4 from the microsd, but you can do easily from USB stick from the bios (press ESC during the boot and you can change the boot sequence in the bios).
You will need two usb sticks: one with a bootable Debian 8 installation image and one empty, where to install Debian.
First make a full backup of windwos 10.
After downloading the Debian 8 amd64 iso image (http://debian-8.6.0-amd64-cd-1.iso/), create a bootable USB pendrive with Debian 8 (there are plenty of tutorials and softwares to do it). Than from the bios, boot the system from the bootable USB. Attach a second USB stick (32gb are more than enough) and start installation process: you will need a basic Debian installation, avoid environmental desktops and all the other options, except SSH.
When you are done, do the following in the terminal (root user):
echo "deb http://packages.openmediavault.org/public erasmus main" > /etc/apt/sources.list.d/openmediavault.list
apt-get update
apt-get install openmediavault-keyring postfix
apt-get update
apt-get install openmediavault
omv-initsystemIgnore key error and during installation,the system will ask about MD arrays: just put "none". For all the rest choose the default options.
Reboot and... OpenMediaVault is installed,you are ready to login!
