I'm not so expert.
I read this guide:

How can I insert these values:
"-v (optional, shows you what is happening)
-x (safe mode, to get it to install)
npci=0x2000
GraphicsEnabler=Yes (this is specific to my Nvidia 8600, you may or may not need this)
UseKernelCache=No (Yes was causing kernel panics)
cpus=1 (From the X99 guide, to get the installer not to crash)
