Thanks, It all worked, until clean install windows and it needs to use the Encription key, which I do not have. Tried to contact the guy I bought it from, no help from him.
Thanks anyway for you...

Thanks, I might have a major problem, shifted house and cannot find my install disks/USB, same for Backup.
An other matter, I cannot even get to Safe start etc.
Thanks again
