Windows 7: BitLocker (USB)

Enabling Bitlocker on a Windows 7 Machine with a USB Key

Step 10: Click "Save the recovery key to a USB flash drive". You may also choose to create a backup key using one of the other methods. A copy of the recovery key will automatically be sent to an NAU database.

Note: If you choose to create a backup key, keep it somewhere safe and secure. It should not be kept near the computer it unlocks.

Step 13: Insert the USB flash drive that you intend to use as the key into the computer and restart the computer. The computer will automatically verify the flash drive and begin the encryption process.

Note: The encryption will likely take several hours to complete. The computer may be used as normal during this time. If the computer is shut down, the encryption process will pause until the computer is turned on again.
