Dual boot to windows 7
I have Ubuntu 12.10 dual booting with Windows 7.
How can i change Windows 7 to my default operating system? Right now it automatically boots to Ubuntu with no screen displaying what one to choose. The only way for me to get into Windows 7 is to press f12 at startup select my hard drive then grub decides to show up and I can select Windows 7 from there.
