Secure your hard drive with Windows Vista BitLocker

Minimum requirements

Before we start, we must meet the minimum requirements for BitLocker encryption. Here are the two basic options for running BitLocker.

The 1.5 GB Active System partition is where the unencrypted bare essential bootstrap files for the Vista operating system are located. The 50 GB Boot partition is where Windows is installed and where your page files and temporary files should be located, since EFS can't protect these things but BitLocker can.
