Default Can't boot back to Windows 8

Have LinuxMint 16 dual boot with Windows 8. At first I had to boot to Windows and then shift restart to boot to LinuxMint. Now I immediately get a boot screen that says Windows 7 and that's it. Highlight Windows 7 hit enter, nothing just brings me back to the same boot screen. After trial and error I finally got back to LinuxMint. I think when I downloaded grub 2 and tried to config is when things went haywire. Can anyone help me so that I can boot to Windows 8 again.
