I have erased my old win xp instead of install the last release of Navigatrix in dual boot as i used to.
I'd like now to recover some files and install win XP in a virtual machine for some programs I don't find in Navigatrix (create kap files from google earth)
I've looked in ubuntu documentation but in the terminal I get a message that I don't have the rights of super admin or something like that.
Any help?
Thank you

You can get administration rights with the command "sudo su".
