I did find the Boot Camp app under "Program Files" and ran it. From the Windows desktop that does work, I noted that there is no D: drive (no MacOS partition), and there is no "Boot Camp" app in the Task Bar ^ menu. One works and launches the Windows 10 desktop, the other produces (Windows-based) error messages and offers to fix the corrupted drive instead.

He gave it to me to have a look, and here's what I found:ġ- Windows boots fine, but there are two Windows 10 installations to choose from on startup. Since doing so, he has been unable to boot back into MacOS. My friend's teenage son installed Boot Camp on his 2019 MacBook Air. Cannot boot or recover MacOS (even from USB installer drive or internet) after Boot Camp installation Hi all - I have searched the forum but (so far) cannot find any answers to this particular problem.
