You should be able to do this booted off a LiveCD. If you have settings and things you need to retain, copy your entire home directory: /home/{yourusername} Once you have 1 or ideally 2 copies of everything, I recommend that you wipe, reformat and reinstall from scratch. -- Liam Proven • Info & profile: <a href="http://www.google.com/profiles/lproven" target="_blank">http://www.google.com/profiles/lproven</a> Email: <a href="mailto:lproven@cix.co.uk">lproven@cix.co.uk</a> • GMail/GoogleTalk/Orkut: <a href="mailto:lproven@gmail.com">lproven@gmail.com</a> Tel: <a href="tel:%2B44%2020-8685-0498" value="+442086850498">+44 20-8685-0498</a> • Cell: <a href="tel:%2B44%207939-087884" value="+447939087884">+44 7939-087884</a> • Fax: <a href="tel:%2B%2044%20870-9151419" value="+448709151419">+ 44 870-9151419</a> AIM/Yahoo/Skype: liamproven • MSN: <a href="mailto:lproven@hotmail.com">lproven@hotmail.com</a> • ICQ: 73187508 -- ubuntu-users mailing list <a href="mailto:ubuntu-users@lists.ubuntu.com">ubuntu-users@lists.ubuntu.com</a> Modify settings or unsubscribe at: <a href="https://lists.ubuntu.com/mailman/listinfo/ubuntu-users" target="_blank">https://lists.ubuntu.com/mailman/listinfo/ubuntu-users</a> </blockquote></div> Actually some of the files permissions are set to 000 (by me ) and i am not able to change them . i changed them (before) to stop unauthorized access . i am not able to copy them and they are of great importance . thanks for help c009
