I did. I partitioned the drive beforehand, and it said there was 2xx of free space, which is what I partitioned. So I clicked install on that drive, and with / as the mount point, and it installed. It gave me a Windows 7 option when I booted, so I figured I was fine and continued to mess with it. But nooo, apparently 2xx of free space means what Windows is installed on. Makes complete sense.
