How do i fix this problem???
If you have run Bootcamp created Flash/DVD/CD against the Windows OS than you have BootCamp in Control Panel where you can assign Mac OS space as Target/Default Boot. If you do not see it there and you did not disable/offline it then Mac OS is gone?
Reboot, hold the option key down as soon as you hear the chime, report back as to what is shown in the boot manager.
