If you're determined to get it to run on your DIY HP setup, why not just take the internal SSD out of the HP, put it in your Asus, install from the USB PP 2 stick to the SSD using the Asus because you know it works on that motherboard. Then when the install is done, simply move the internal SSD back to the HP?
Or ditch the HP and use the Asus as the controller.
