I've dragged everything off the Windows bit of the hard drive - Ubuntu let me browse to it automatically. Genius. I can even automatically connect to both the Macs and the PC's in the office. I've got everything I need off the Windows bit so wanted to free up the space. After a brief thought I figure just to install Ubuntu again and use the whole hard drive. No worries there.
I have come across a problem though. The sound isn't currently working and I need to look at that. Still, insofar as what could have potentially gone wrong it's pretty minimal so far.
Edit: It's because I didn't plug in the speakers. Dickhead.
Enjoying fiddling around with it to be honest.
