If you click 'Yes' you will then be prompted to put a tick in the box next to the partition you wish to full disk encrypt, you will need to save your admin password to either a network or removable media drive. You will need to either type or copy (from your network/removable media drive) then password and then supply your full disk encryption username and password and then click 'Encrypt'. 

After clicking 'Encrypt', if you are seeing the following error message,
