You can install that with Bootcamp and have Windows on its own. HOWEVER tomorrow it all changes as new models of Windows PCs roll out. So I'd start over.

About HP. For me my last HP was my last HP as they walked on the warranty at 3 months. The machine went to them, came back locking up in 5 minutes. Calls were responded with "We've done all we can" and worse. After 6 months of surveys and more the sign was clear that HP was not going to honor the warranty. My last HP anything.

This would be a disaster for some but I was lucky it was for work so get another laptop and move along.
