The unit ships with a cd/dvd drive and also has usb ports. Download the install media for the version of Linux you would like then either burn a cd/dvd from the iso or follow the distributions guide for creating a bootable usb stick from the device. Boot the system from the device you created (change bios to boot from cd/usb or set a temporary boot device). If you want only Linux on the system, perform a normal installation, otherwise follow the distributions guidelines for dual booting with Windows.
The hardware itself does not appear to have any exotic elements according to the HP website listing of the system specs so your setup should be no different for your all in one than it would be for a normal desktop pc with wireless.
