Recovery Media Software For Advent 8109 Laptop Wanted?

Hi, I hope someone can help me solve my problem. I'm trying to find the recovery software for my laptop, as detailed above. Dixons, from whom I purchased the laptop, have offered to sell me the software for just under �40, but I don't feel I should pay for this, as the laptop is still under warranty. Has anyone any suggestions as to how to acquire this software, without cost to me? I thank you in advance for your answers.
