I bought a HP with no OS, can I easily install new one on hard drive?

Buy it and install it.

You will need to purchase one, but sure. It's easy.
Or Linux for free.

as it an hp prebuilt check to see if it needs any bios updates to run the newer os. some of the older perbuilt cant run newer os due to bios issues. check with the hardware vendor support page before you buy any os.
