multiple boot

Yes, possible.

Install Windows 7 first. If you want it easy, don't use UEFI firmware. Set your PC to BIOS, and don't change it afterwards. Leave unallocated space on your HDD for Fedora (and Mint).

In case you want Mint because of one of their Desktop Environments (DE), and not because of the underlying Debian, I would recommend you to install only Fedora Linux and (in addition to Gnome, or whatever DE you choose) your favorite Mint DE (Cinnamon, Mate). They are all available in Fedora repositories, or as Spins: KDE, Xfce, Lxde, MATE, Cinnamon, etc.
