@DeeDooDaa8 - regarding SD card size, Raspbian is OK on a 16GB card. I've been asked to provide Piratebox as a PINN install before, but I've not got around to it yet. It looks relatively small in itself, so you should be able to install them both. However, PINN shares any free space equally between the OSes, so you end up with around 8GB for each of the OSes. This is getting rather small for Raspbian now, so it depends what you want to do with it. Also, given Piratebox is used for file sharing, it depends on how many files you are going to share and where you will store them (on the SD card, or externally). If you are storing files to be shared externally, then you can probably adjust the SD card allocation of both OSes, but this is more of an advanced subject.
