Unfortunately, there is nothing we can really do but for you to buy another recovery disk from Toshiba.
Each laptop has its own serial number and a different product key for its Windows Operating System. So, it's not really possible to obtain someone's eles recovery disk because it most likely won't work due to factors including Windows Activation etc.
However, there's an alternative. You can buy another recovery disk from Toshiba's European site: https://backupmedia.toshiba.eu/
