Hi:

The product specs indicate that it came with W8.1 from HP.

The product key is in your notebook's BIOS.

If you want to view and print out the W8.1 product key and the version of W8.1 the key is good for, install and run the free Showkey Plus app from the Microsoft Store.

Get ShowKeyPlus - Microsoft Store

You need to install the same version of W10 that the W8.1 product key is good for.

For example:  if the Showkey plus report indicates that the notebook came with W8.1 single language, then you need to install W10 Home Single Language, and when you are asked to enter a product key, you select the 'I don't have a product key' option.
