snow on HP 6720s - can't install

[nimaatsed]

i have a HP 6720s laptop with an intel core 2 duo @1.6 G, 3 gb of ram, integrated video card. i try everything i read but it just can be installed. a try using a stick,a dvd dual layer and a stick and a dvd, but nothing (http://www.infinitemac.com/f57/guide-boot-retail-snow-leopard-dvd-usb-pc-t3859/). when loads, on the screen appears chameleon an i have to choose between "Mac OS X" -volume where mac is installed and "Untitled" - ? i think the installation dvd. after i choose the second variant on the screen apears "can't match kernel with cpu" error. what do i have to do in order to install mac snow leopard.
my only operating system is Mac Leopard 10.5.6

If I am correct, you have to partition your HD and install SL there and modify it to be able to boot with correct kernel (a modified one of course, ie Vanilla)
