First off, learn even the basics. Your video tells us nothing. Learn to use verbose mode, learn what command line switches you might need to use.

To start you off, make sure your USB stick is in a USB2 port. That can help get past "waiting for root device" errors. Second you may need a DSDT for your motherboard to have working keyboard support so you can actually install. You can use a pre-made one for the same model or generate one from your own hardware. Put it in /Extra. Since you probably only have a Windows OS now, you can use Transmac or MacDrive to edit the contents of your USB stick. Follow tonymac's guide to install.
