I installed Ubuntu on my laptop which when I got it I had Fedora 13 installed on it as the OS. Now I want to install Fedora 18 in a dual boot with Ubuntu. Problem is when I installed Ubuntu, I didn't partition for dual boot and I gave the entire hard drive to Ubuntu and no longer have the space to dual boot. How can I lower the partition on Ubuntu to make space on the hard drive for Fedora? I want to split the hard drive 50/50 between the two. Thanks in advance.
