You are preparing to install Windows 7 on a new computer. You need to enable BitLocker for encryption. What is required in order to enable BitLocker?

FAT32 is an older file system that does not support the advanced features, security, or large file/partition sizes required by BitLocker.

A smart card can be used as an optional unlock method for BitLocker, but it is not a prerequisite for enabling BitLocker itself.

BitLocker Drive Encryption requires the system drive and any data drives to be formatted with the NTFS file system. NTFS provides the necessary file system features and security attributes that BitLocker utilizes for encryption and integrity checks.

While a Trusted Platform Module (TPM) is recommended for BitLocker, it is not a strict requirement to simply enable BitLocker, as it can be used without a TPM using a startup key or password.
