Hello Tempers. When my bro gave me his laptop, he installed a cracked version of Windows 7 on it. When I turn it on, I have dual boot for some reason. (both options are Windows 7, but only the top one works and the second one is empty) I'm curious to know how I can remove the second one because I want to have Ubuntu as a second option. (I'm guessing you can only have to operating systems) So for the time being I'm stuck running Ubuntu off a USB. Thanks in advance.
