A choice of starting volumes will be displayed. Choose the new one and follow the Welcome instructions of the new starting system . When you will be asked to migrate your old data from, choose "a Mac, a Time machine Backup or Startup disk". See also these Apple instructions: https://support.apple.com/en-us/HT204350
