Hi, Bob:
With business notebooks you have to call HP by telephone to order recovery media.
In Canada and the USA you can call this number... 1-800-334-5144
You can also reinstall W8.1 for free by making your own W8.1 installation media from the link below...

I have zipped up and attached below the Microsoft utility you can use to transfer the ISO file to a DVD or USB flash drive, so that it is bootable.
Then you can install the drivers and available software from the notebook's support page.
