i was very disappointed to find these new machines that don't boot Linux easily.  i have to wonder if HP received rebates from M$ by making it difficult to boot Linux on these machines.  These machines have to be noob proof.  $300.00 less expensive than the same CPU and intel chipset as Dell.

To boot off of a knoppix disc use the boot option knoppix acpi=off.  
For CentOS, use linux pci=noacpi,nommconf.
