My sister uses XP via VMware Fusion on her Mac. I set it up for her about two months ago, originally allocating 5GB of space for Windows. I figured that would be enough as she would only be using the web and I've used computers with far less actual space than that before. However, I underestimated the size of Windows. I've tried increasing the space by using vdiskmanager GUI, but I always get an error message. I've tried using the command line it generates in Terminal, but that doesn't work either. I also followed all of these instructions. I've done trial and error for two and a half hours and I'm stumped. What is wrong? Thanks.
