I am wondering how I would go about uninstalling the entire Windows 7 operating system off my Mac, it is hardly used and is taking up space that I could otherwise use for more important things. Any help is appreciated. Thanks.
open parallels and in the parallels virtual machines window, control-click on the virtual machine you want to remove and select "Remove" from the drop-down list. make sure you select "Move to Trash" from the dialog. empty your trash and the space should be freed up.
