Soon after the first Intel-based Mac was released, Apple launched BootCamp, a tool that allows the Mac users to install and boot the machine into Windows natively along with existing MacOS. The tool makes the machine more efficient to run performance intensive apps and programs. In short, BootCamp is used to dual boot Windows and macOS on Mac machine.

After installing Windows, you might not be able to see BootCamp Partition in MacOS. In case, you try to access the drive using Disk Utility, the partition will be greyed out. The partition is NTFS formatted, though they will appear as FAT formatted. When a partition is removed, added or resized via Windows setup, the details get updated in Master Boot Record (MBR).

This information doesn’t sync to GPT (GUID partition table) record. The reason behind this behaviour is that when a partition is added, resized or removed the GPT or MBR partition schemes get confused and Windows show OS partition.
