You can download a netiso (net install / minimal iso). That kind of ISOs are between 80-250 MB (or even less) and contains a base system only but you can download the "rest" of the system from internet.
I tried booting from a live cdr but it loaded into a command line. Is there a way to get this with a GUI installer? I'm new to Linux and don't know the command line.
I though in that. I love that distribution it's excellent but it has it problems. I wouldn't recommend to "install" it in a hard drive as probably wants OP.

But If you are not confident enough with Linux perhaps you might consider other options.
