I have this situation. whereas the actual is 7.62 GB then i tried to execute the steps given from here Geekwebsite. to make it bigger to 14GB (which is 13.92GB)
Everything smoothly working... until i decided to use GParted Live cd as well to expand the remaining freespace to be used.
Once I finished using GParted, no error found. I boot up my Linux (guest). And,... login into it... strange thing happened. The size seems not changed at all?
Look : 
What the things (steps) i forgot to do?
