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 the Windows operating system partition (usually drive C) only. 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 booting to Windows 7 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 tools. 7. Wait until the encryption process completes. After that, you can use the Rescue and Recovery program to perform backup and restore operations.

When setting up BitLocker in Windows 7, the BitLocker partition should be 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 settings. 2. When restoring a system that is using Windows 7 and BitLocker, a message will display, indicating that there was an error at shutdown. The message can be ignored and everything should operate normally. 3. For OEM or non-Lenovo standard preload systems, you need to suspend the encryption of the Windows operating system partition when performing any backup or restore operations using the Rescue and Recovery program, otherwise the Rescue and Recovery program will not enter PDA. 4. You might need to clear the TPM and encrypt the partitions again after restoring the system from a backup with BitLocker encryption. 14 Rescue and Recovery 4.3 Deployment Guide
