    There is no upgrade/downgrade path. You must do a clean install of the OS. If your data is on a different partition than the OS, then yes it's safe, otherwise, no.

    So I must re-install all of my program if my OS and program files partition is same? And how do I know the partition details on my PC?
  3. You have to reinstall all your programs regardless of partition. You asked about your data (pictures, videos, documents,...), not your programs.
