Hi, Mike:
I do not believe HP sells recovery disks directly to those who do not live in the USA or Canada.
They contract with an e-partner who sells the recovery disks to those who live in Europe.
Below is the link to order a set for your PC. They are pretty pricey.
You can try calling HP direct and see if they do sell them at the following phone number:
