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. Here we recommend that you choose BitLocker to encrypt the Boot Camp 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. The partition created by Boot Camp Assistant for Windows during this process is called the Boot Camp partition, it is an NTFS partition. 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.
