Failled to install 2 programs.Warning-box appeared.

[John Guri]

Am new to 10.10.Ran a terminal command previously,to install restricted formats package.Most of package seemed to have installed,but terminal stalled and couldn't seem to finish.A Microsoft-dialogue-box appeared,asking me to agree to accept the usual ELUA,but with no selection-buttons.Command-line was: sudo apt-get install ubuntu-restricted-extras On checking laptop's HD-files,found a locked file that denied me access.(Wonder if it's a Windows-file: an acquaintance started a Windows7-install,without asking me first,if I even wanted it-some friends,eh?)Install was never completed-Windows7-CD,only run for a minute or so.Also disabled Root-user after this: sudo usermod -1 root John.
