Ok so i tried this once before and it worked I partitioned it but then I didn't like it so i uninstalled and removed the drive(with the - button on disk utility).
Now I have decided against it and are trying to go back to Winbloze..
When I try to partition after repairing Via safeboot I get this Message
Can someone give me instructions for how to do the things in the picture
