Hi,
If you have ordered the Hardware Appliance ,it comes with the OS(linux). then you either need to run the cd\dvd for PI software which you have got along with the box.
if not then you can download the .ISO image from cisco.com then burn it on the DVD and run the DVD.
other way to installed PI is to installed VMware then you need to download the .OVA images from cisco.com and then deploy the ova to your VM.
