Running Windows on 'bare metal' rather than a virtual machine allows you to hook up those odd devices which only have support with Windows driver disks. The major disadvantage of running Windows on bare metal is backing up your data must be done from Windows, you can't just have a snapshot of how your Windows was before you installed that game which borked your Windows installation. You also will probably have to 'fix' your Mint installation after your Windows install, because Windows always assumes that it is the ONLY operating system installed on the system, takes over the MBR, and overwrites any Linux boot loader.
You can also get your Linux portion of the hard disk overwritten if you get one of those 'format the hard disk' type of malware on your Windows box.
