How to Repair BootCamp Partition on MacOS

Summary: The post describes the method to repair C drive in Windows OS and summarizes the procedure to repair Bootcamp Partition on Mac hard drive. It also suggests a third-party tool to optimize and repair Bootcamp Partition automatically.

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 OS 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 grayed 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 gets updated in Master Boot Record (MBR).

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

Another way that the CheckDisk used to locate errors on C drive is by making a comparison of the volume bitmap with disk sectors being assigned to the files in the file systems. Check Disk fails to perform repair operation on the files containing corrupted data, but structurally found intact. Check Disk command with appropriate phrases can be executed either from the command line prompt or the interface.
