I'm a beginner with the Raspberry Pi and know little about it, so please bear with me. I was trying to install Kali onto my Pi, so I used my PC to format an SD card and load what I assume is the image file (extension .img.xz) onto it using the Win32DiskImager. When I inserted the SD card into my Pi and plug it in, however, it wouldn't boot up.
Is there something wrong with the way that I'm trying to load the card? And is there any better way to install Kali -- perhaps using NOOBS?
