When you set up your disk partion when you installed Ubuntu did you leave any space or does your one partition take up the whole drive? – John S Gruber Aug 5 '12 at 5:10

You can try gparted, but partitioning a system that is already installed can destroy it. For best results, run the installation again, and partition the drive from there.

by running installation again, any chance for damage in data? – anilkumar b Aug 5 '12 at 3:43
It will usually clear all data. The reason to do it is that re-partitioning has a chance of deleting important data, so by re-installing you know at least the system will work afterward. You need to back up your data either way. The answer tijybba linked to is probably better than mine actually. I try to avoid partitioning so I don't know what the chances are of breaking the system. – Wegko Aug 5 '12 at 4:21
