mostly when you buy a PC from a big manufaturer like HP they put their own limited version of the BIOS over the Acutual Bios.

best bet would be to unplug your PC and locate the small battery (about the size of a penny and 3-4mm deep) on your motherboard...remove this taking care not to touch both the top and bottom of it at the same time. Then wait for 5 minutes or so and replace it..

This will flush the Bios on the motherboard back to Factory settings.

However it will only change the bios, not anything in your OS.
