Hi,
Without disc it looks like restoring back to factory default state is the only option.
I mean doing like you did here. If that isn't possible then you have to reinstall the operating system.
a friend came down and used something like "key something" to restore back to factory can you give me the link for "psi" to keep upto date thanx for your help keep up the good work :thanks:Sorry but I don't have personal experience of reinstalling operating system other than from normal installation disc. I recommend to take system to local computer repair shop if you can't launch restoring to factory default state like you did earlier.
