3. Wait for a while for the BitLocker initialization to complete.

4. Select Use a password to unlock the drive and specify your password. Re-enter the password to confirm and then click Next .


5. Choose where you want to save the recovery key needed to access the drive in case you forget your password. Here there will be 4 options for you to save passwords.
     1. Save to your Microsoft account, Save it to your Microsoft account (make sure your microsoft account is linked to your computer)
     2. Save to a USB flash drive, store it on a removable USB device (make sure you have 1 usb plugged into the computer to save the password)
