How to edit Kali Linux image file

Although I'm gradually getting to the point of installing kali on my Raspberry Pi I still have several issues to over come.

Firstly, the image I have will only boot to the Username and Password screen where it sits doing nothing. I now need to edit the image in windows to change the password and username so I can continue the booting process past that point.

There must be a way to edit the image to change these settings.

Thanks.
