What OS the computer came with is irrelevant. What matters is the hardware, and whether it's compatible with XP.
You need to check the HP web site and see if XP will work with your laptop.

When I was trying to install Windows XP on my HP Pavillion Laptop, before setup I got a STOP: 0x000000CA and sometimes 0x0000007B error. How do I fix this?

2018-04-19T17:17:58+00:00 If it came with Windows 8, it's possible XP may not be supported on the hardware. You might want to check HP's web site and see if XP will even run on that model.
People have done it on Windows 10, by changing the SATA to IDE. My computer does not have a SATA node.

If not, what was originally preinstalled on it?
Windows 8, I think...
