Here are the steps I used to increase the size of the Windoze partition: You will need your windows install disc (or recovery disc) It became too small to hold all the games that are getting installed :( AND the Mac partition had lots of empty space. How did I resize the Windows 7 ( Win7 ) BootCamp partition on my (kids) MacMini? I have a 2011 MacMini with a 500GB HD that has a 60GB Partition for Windoze7 created by BootCamp.
