Hello... Typically when they are sent/bought there are the files and utilities on the HD to do this... seeing how old it is are they still there in the D:\ (recovery)partition?
They can also be bought from Toshiba through their website for your model...
Have you downloaded the manual for laptop yet? there would instructions there IF... the files and utilities are still on the one of the HD's B /
