First you need to install the image on your hard drive or SSD. How you install depends on the media you are using. See the image installation instructions here.
A USB key is one of the fastest and easiest ways to create boot media. You only need a fat32 formatted USB key. Most USB keys come formatted with fat32. It's OK if there are other files on the USB key as long as there is enough room for the image files.
These instructions are for a Windows computer. You can do this on Linux but it's a bit more complex (instructions here)
WARNING: Installing an image will erase all data on the target computer
Once your image is installed you will need to resize the partitions
Boot your new VortexBox and log in from the command console (user: root password: vortexbox)
next update to the latest code with the command
dnf -y update
now you need to expand your root partition to 30GB type
config_4-30.sh
and finally fill the rest of your hard drive with the storage partition with the commands
config_local_storage.sh reboot
Your VortexBox is now ready for use.
