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

32-bitbootcamp

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.

You can set the default boot partition from the option-boot screen. Press the Control key while clicking the arrow beneath the drive, and that should do the trick.

I finally solved it!

This literally took hours out of my day, but I now know what the problem was. It turned out that the drivers actually were installed. by verified this checking for the presence of the following files:

C:\Windows\System32\Drivers\AppleHFS.sys
C:\Windows\System32\Drivers\AppleMNT.sys

The reason that the drive was unreadable is because they were encrypted with FileVault. I disabled FileVault in OS X, and when I booted into Windows again, the partition was mounted.

There might be a way to use FileVault and Boot Camp together, I'm not sure. I read in a few places, however, that if you enable FileVault after installing Windows with Boot Camp, you can have your drive encrypted and accessible from windows. (This is just a hunch however, I'll have to look into it more)
