How do you make a partition modifiable that says it can't be modified?
When I first set up Windows 7, I gave it way too much of my mac's memory. Now I want to lower the amount of memory it has, but it says it cannot be modified. I can only erase the disk. How do I make it so I can modify the amount of space on my Windows disk without erasing it and redownloading it.
