A similar question has been asked here: Bootcamp stuck in Windows, but mine is a little different - the answer did not work for me.
I have a MacBook Pro 13,2 that is running 10.13.1 and has a Boot Camp install of Windows 10, Fall Creator's Update. (don't know version number atm)
Switching to Windows is easy. Hold option while I boot, enter the firmware password, and I can select the Windows partition. However getting out of Windows is not easy.
I have the Boot Camp toolbar menu visible on Windows, but whenever I press Restart in macOS, it tells me that the macOS volume cannot be found.
To get out of Windows earlier when I had this problem, I would reboot into Windows Recovery, which takes no time at all then press turn off the computer. My Mac would reboot into macOS just fine.
Now, the only way that I can find out of Windows is to reboot into macOS recovery, which takes a few minutes to load.
Why can't I use the Boot Camp toolbar menu to return to macOS? How do I repair that?
Some notes about my system:
- FileVault is on
- Firmware password is on
- BitLocker for Windows is off
- An NVRAM reset does not work while in Windows
- Boot Camp utility in Windows does not show any volumes other than the Windows volume
- macOS partition is in APFS
- macOS version 10.13.1 (17B1003)
