I have a Mac Mini 2011 running OS Lion. I ran boot camp and installed windows 7. Then I had change in mind, I uninstalled it. Problem I am having now is when I hold the option key at start up for boot selection windows drive is still there even after uninstalling and formatting the drive. I even tried formatting uninstalling OS Lion. Format my hard drive partitions also. For some crazy reason windows icon is still there. When I login to windows icon it gives me this error (boot selection failed because a required device is inaccessible). I am trying to figure out how to remove that windows icon from the boot selection.
