I want to delete all the data on the mac partition, while keeping the Windows side untouched. I will be reinstalling Mac OSX on a new partition. I want to make sure I'm good before I do anything. Do I simply delete the partition and create a new one? Or will that affect the Windows partition? I know that doing this for the Windows side will be safe, but I don't know if I can split the Windows partition after deleting the Mac side.
