BitLocker's sole purpose is to prevent anyone from bypassing the login screen by pulling out the hard drive, rewriting the password, and putting the hard drive back in. In this case, the disk encryption employed is not really a "true" encryption, instead, it's an extension of operating system's authentication mechanism. On boot, the key is automatically filled in by hardware (TPM for BitLocker) when some conditions are met, no passphrase is asked. The second approach, which is popular on phones and tablets, is to use disk encryption transparently, usually with hardware assistance. The disadvantage is the need of entering (very long) keys manually on boot. The system cannot even boot without the correct key because the underlying hard drive is inaccessible. The first one is the traditional approach: The encryption is applied independently from the operating system. There are two approaches to full disk encryption.
