Short background: I got my intel-based powerbook pro about a year ago and I love OSX so much I realized I wouldn't need my windows partition very much. I allocated it 6 GBs (which is essentially nothing and I cannot save anymore files on that side cause its full). I enlisted in a programming class for ArcGIS this semester. The class uses VB and ArcGIS which only run on PCs. We have free year long student editions of these CDs that I cannot install on OSX. I want to install them on my PC partition but I have no memory. What can I do? Is it possible for me to repartition without having to completely reinstall everything on both sides of the partition? If not, can I just delete the PC partition and create a new one an only reinstall that side? I am looking at buying a new back-up hard drive, is it possible to store both PC and mac files on that? I know that will my last back up hard drive I could not get this to work correctly. My first post, so sorry if I am in the wrong place or repeating stuff thats been answered. I tried searching for an answer before posting but couldn't find exactly what I needed.
