Contact Toshiba and order a new set of recovery discs. If you have data on the hard drive you don't want to lose and don't have backups for, get ahold of something like Linux Mint, burn it to a DVD, boot from it and copy your data to a flash drive.
You can download Linux Mint from here:
https://www.linuxmint.com/download.php . You don't have to know anything about Linux because it has a user interface similar to Windows. And you don't have to install anything, just boot from the DVD and you'll be up and running in under 4 minutes.
Good luck.
