The only way i know to get recovery media is to purchase it from the manufacturer, if the laptop came with windows 8.1 or 10 then the key should be stored in the bios, just download the ISO from microsoft and reinstall it yourself, windows 8.1 and 10 are very good at installing drivers for you and if it doesnt then you can browse Toshiba's support site and download the drivers for what is missing.
You can download a windows 7 iso from microsoft too, but you will need your product key, if its on the bottom of the laptop. and you will also need to get your own drivers
