Error uninstalling CTM now won't boot

I ran Time machine for several weeks. Went to uninstall today. Had to reboot. Error message when rebooting regarding Time Machine. Computer wouldn’t boot up past bios splash schreen. Used Windows 7 disk to repair hard drive. Now my computer can’t boot up because there is no “bootmgr”. I’m ■■■■■■■ big-time.
