You state that it's a MAC running W7 . That tells us it is using a program to boot into W7. Which program is it using? Is it Apple's Boot Camp or a seperate program like Parallels?

 

yes it is apples boot camp

 

This should help

Boot Camp is set to boot into Windows. Just need to change it to your preference..
