I am brand new to Ubuntu (and installing operative systems/partitioning/etc...) and up to know everything has been going smoothly, but now I'm having a problem that I think I can fix, but just don't know how...
I wanted to have a dual-boot, so I installed Windows and then Ubuntu in separate partitions. My disk available space is about 580GB, I gave 230GB to Windows and when installing Ubuntu, I set up a partition of 120GB with a 8GB swap space. The problem I have now is that Ubuntu took all the remaining space in my disk. I wanted the remaining 230GB to be a partition to keep my files.
So, what I tried to do was to resize (reduce) the Ubuntu partition from the Ubuntu Installation CD. I started GParted after running the "Try Ubuntu" option, made "swapoff" to the swap partition, reduced the size and then applying the operations... up to know everything seemed to work, just that the computer turns off itself after five minutes or so when applying the operations.
I tried this several times with no success. Now I'm afraid I won't be able to make the resize operation... I don't adventure into any other possibilities, since I'm afraid to screw up my boot. What am I missing? Is there any other alternative I can use?
