What is Boot Camp partition? Boot Camp is a solution provided by Apple that allows users of Intel-based Macintosh computers to install and run the Microsoft Windows operating systems. Boot Camp helps users partition the disk and install Windows to the partition, and helps users install drivers for Apple hardware to ensure that users can run Windows properly on Mac computers. In the process of installing Windows using Boot Camp, the partition created by the Boot Camp utility that used to install Windows is the Boot Camp partition.
What is BitLocker? BitLocker is a full-volume encryption feature built into Windows Vista and later operating systems. Windows users typically use it to encrypt hard drives and protect important data from unauthorized access. In Windows Professional and Enterprise editions, you can use BitLocker to encrypt drives directly. However, this feature is not available in Windows Home editions.
How to encrypt Boot Camp partition with BitLocker in Windows Home? BitLocker encryption is not available in Windows Home Edition. Therefore, if you are running Windows Home on your Mac, you cannot use the built-in BitLocker feature to encrypt your Boot Camp partition. So, is there another way? Yes, use a third-party BitLocker solution: Hasleo BitLocker Anywhere. It is the world's first BitLocker software designed for Windows Home, allowing you to encrypt your Boot Camp partition with ease.
Step 1. Download and install Hasleo BitLocker Anywhere.
Step 2. Launch Hasleo BitLocker Anywhere, right-click the Windows drive letter (usually C:), then click "Turn On BitLocker".

Step 3. In this step, you are asked to choose how to unlock the Windows drive at startup. You can choose to enter a password or insert a USB flash drive each time you start your PC.

If you choose to enter a password at startup, you are required to specify a password for encrypting the drive, enter the password and click "Next". You should choose a password having a combination of upper and lower case letters, numbers, spaces, and special symbols.

If you choose to use a USB flash drive for startup, you will need to specify a drive to save the startup key. Select a USB drive and click "Next".

Step 4. After clicking "Next", you are asked how you want to backup the BitLocker recovery key. You can save the recovery key to a file or print a copy of it, then click "Next" to move on. Please note that anyone can use the recovery key to gain access to the drive, even if they do not have the startup key or password created in the previous step, so please do not disclose it to others.

Step 5. Now a pop-up will appear asking you if you want to reboot into Pre-OS to encrypt the Windows partition. Click "Yes" to continue.

Step 6. Another pop-up will appear asking you if you want to build a WinPE image to continue. Click "Yes".

Step 7. Hasleo BitLocker Anywhere starts building WinPE. This may take several minutes, so please be patient to wait.

Step 8. After successfully builded the WinPE image, Hasleo BitLocker Anywhere will prompt you to reboot the computer, click "Yes" button to allow Hasleo BitLocker Anywhere to reboot your computer.

Step 9. Hasleo BitLocker Anywhere will now reboot and enter Pre-OS to encrypt the contents of the selected drive using BitLocker drive encryption. The encryption process could take a long time to finish depending on the size of the drive, so please be patient to wait. If you don't want to wait until the encryption operation is finished, "Shut down the computer when the operation is completed" option is a good idea. Just check it.

Step 10. After the encryption is complete, click the "Finish" button to close the window.
