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.
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
For VortexBox 2.3 use
yum -y update
For VortexBox 2.4 use
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.
