3. Install the Rescue and Recovery program and restart the computer.
4. Start BitLocker from Control Panel and choose the partition to encrypt.
Note: It is recommended to encrypt only the Windows operating system partition (usually drive C).
5. Click Turn on BitLocker, and follow the instruction on the screen to encrypt the chosen partition.
After that, a recovery key is automatically created.
6. Save the recovery key to a USB storage device.
Note: Keep the USB storage device in a secured place. The recovery key is needed when you want to
boot to the Windows Vista operating system or the Rescue and Recovery workspace. The BitLocker
encryption will be lost if the hard disk drive is cleared by the Diskpart commands or other hard disk
drive tools.
7. Wait until the encryption process completes. After that, you can use the Rescue and Recovery program
to perform backup and restore operations.

Notes:
1. When setting up BitLocker in the Windows Vista operating system, the BitLocker partition should be
placed after the Windows operating system partition for best results. If it is placed before the Windows
operating system partition, the partition number will need to be updated in the Rescue and Recovery
ADM file.
2. When restoring a system that is using the Windows Vista operating system and BitLocker, a message
will be displayed, indicating that there was an error at shutdown. The message can be ignored and
everything should operate normally.
3. You might need to clear the TPM and encrypt the partitions again after restoring the system from
a backup with BitLocker encryption.
