I created a bootable USB Stick with Ubuntu 13.10 and when i boot from it and try to install it i only get the option "Install inside Windows" and the button in the bottom right corner says "Restart to continue". But i don't want that, i want a real dual boot. I installed Ubuntu few days ago on my laptop and i clearly remember that it said "Install ALONGSIDE Windows". What should i do to get that option? PS i previously had Ubuntu installed on this PC from WUBI, but i uninstalled it.
