Only Macintosh shown on Startup Manager after Windows 10 32-bit Boot Camp install


I installed Boot Camp with Windows 10 32-bit, but it doesnt give me the option to switch my Mac into Windows. Any help? I've tried holding option when restarting it but only the Macintosh box appears.

32-bit versions of Windows 10 are not supported on any Mac model. You need to install the 64-bit version.

From Apple KB: How to install Windows using Boot Camp

Before you begin, make sure you have everything you need:

  • An Intel-based Mac
  • A Microsoft Windows installation media or disk image (ISO) containing a 64-bit version of Microsoft Windows 8 or later

See this list for which Mac models support Windows 10.
