Bootcamp does not boot MacOS after reestart.

[maaribeiro]

I installed Bootcamp with no problems.
Now, after reestarting with alt pressed, there is no option to Boot in MacOs.
The system reestarts in Windows.
Any help?

If you don't see a macOS partition when you boot up with the option key pressed, then its probable you installed windows over your macOS partition.

Reboot and hold the cmd-r keys down and that will boot up into the recovery partition. You can then run Disk Utility and see what the partitions look like

It is not working. Rebooting with comand-r keys still keeps the windows reestarting. I still can't see the partitions.
The bootcamp partition has 70GB.
[doublepost=1534946298][/doublepost]I went to Control Panel/system and Security/Boot Camp and I could find the partitions.

Disk Warrior has helped me on many difficult situations. However 1) it must be run from an external drive with some Mac OS on it or from a DVD in which it is on top of some Mac OS
2) it must be possible for Disk Warrior to see your faulty Mac volume and if your Mac volume is invisible I see no other solution than reinstall Mac OS and afterwards Bootcamp Windows

I have deleted the Windows partion. Then reistalled Macos, repartion Again. Problems remain.

If you can live with Windows in a virtual machine using VMWare Fusion or Parallels you would always boot in the Mac OS since there would be no other bootable OS.
