Hello good afternoon. I keep a time trying to install Windows, but when I try to install it, I get the following message: "You can create a new partition or find an existing one." I tried and reformat the drive as NTFS, to leave the factory and almost any possible Internet solution; but I can not install it. With other operating systems I do not have the same problem. My current OS is Freya Elementary OS 0.3.1. Thanks for your help.
