How do I rename the Boot Camp partition?
Under default conditions, you'll need to rename the BOOTCAMP volume from within Windows.



In macOS, when the Boot Camp Assistant sets up a partition to install Windows it creates a FAT32 volume named BOOTCAMP.

During the install of Windows, the user is supposed to reformat the volume as NTFS.

By default, NTFS volumes are read-only under macOS and why the renaming, after the install, needs to done from within Windows, unless one has enabled NTFS write support under macOS. This typically requires the installation of third-party software, e.g. Microsoft NTFS for Mac by Tuxera.
