I'm asking because I downloaded the windows installer version, when i open the installer, a window with everything is open and at the bottom say "install" but at middle sais "size instalation" and the max is 30Gb, that will be my ubuntu part in my pc? or after reboot it will say "selec your partition size"? what do you recommend me? its my first time, so its better if I download common installer and try with a CD?
thank you
