Boot Camp Assistant is stuck on ‘create a partition’. I have followed the guide as answered in the question Boot Camp Assistance is stuck on create a partition? but it didn't work after step 8. After I clicked on the "Next" button it says:

Windows detected that the EFI system partition was formatted as NTFS. Format the EFI system partition as FAT32, and restart the installation.

What should I do?

  • You probably should have include the output from diskutil list in your question. Commented Aug 27, 2018 at 7:22

You can try entering the following command in a macOS Terminal application window. This command should format the EFI system partition as FAT32.

sudo newfs_msdos -F 32 -v EFI /dev/rdisk0s1

If the command fails, you could try entering the command while booted to macOS Recovery over the Internet.


when you get an option to select drive to install, delete all the drives you see , untill you only have 1 option ----> " unallocated ".

Installation will go smoothly after you do this
