So, apparently gnome is currently just running from the iso disk image and is not really installed. I started up the installation process and everything was fine until it told me that it wanted to make a partician for itself. I thought that I already delt out the space to it when I set up the virtual computer in fusion. I gave it 20 gb of space to kick around. And now it wants more.
What should I do to get around this? If it does partician, won't it erase my mac files?
