What is Boot Camp partition? If you are a Mac computer user, you may have heard of Boot Camp Assistant, a utility developed by Apple to help users install and run Windows on a Mac computer. When installing Windows on Mac computer via Boot Camp Assistant, the Boot Camp Assistant downloads the necessary support software, creates a partition on your disk for Windows, and then starts the Windows Installer. The partition created by Boot Camp Assistant for Windows during this process is called the Boot Camp partition, it is an NTFS partition.

Why use BitLocker to encrypt Boot Camp partition on Mac?We know that on Mac computers, users usually use FileVault to encrypt partitions to protect our data, but FileVault is only available to encrypt HFS and APFS partitions, it cannot be used to encrypt NTFS partitions, so we cannot use FileVault to encrypt a Boot Camp partition. Perhaps other third-party software under the Mac supports encryption of the NTFS partition, but encrypting the Boot Camp partition may cause Windows to fail to start properly, so we must carefully choose the encryption software. Here we recommend that you choose BitLocker to encrypt the Boot Camp partition. BitLocker Drive Encryption is the built-in disk encryption feature of Windows 10/8/7, so it will not cause Windows to fail to start.

  • Encrypt used disk space only: Allows you to encrypt only the disk space that is currently used by the drive file system, unused space will remain unencrypted, this option can help you save time spent on encryption. After you encrypt a drive with this option, all files that you added to the drive are automatically encrypted.
  • Compatible mode: If a drive that you plan to encrypt needs to be used on Windows operating systems prior to Windows 10 Version 1511, you should choose compatible mode. Windows 10 Version 1511 introduces a new disk encryption mode (XTS-AES) that is not compatible with older versions of Windows, the compatible mode (AES-CBC) is full compatible with older versions of Windows.
  • Use 256-bit encryption: Bitlocker supports 128-bit and 256-bit encryption strength. The 256-bit encryption is more secure but will take up more CPU resources, so you should choose different encryption strengths according to your needs. Please tick this checkbox if you want to use 256 encryption strength.
