I've had that on a work laptop (also an HP). You can try to disable secure boot in the UEFI screen, or you can try and tell the USB stick to treat the laptop like a BIOS machine. The problem is that changing those settings now will break the existing Windows install.
Hi On a recent laptop, Asus X751L, I disabled secure boot. It didn't break windows8 install (to keep warranty) at all.
