I'm a first time noob trying to install this and having a rough go. I'm following this guide however I can't get past step 2

I get a kernal panic which I assume has to do with OpenHaltRestart as it says the getMatchingServices failed. Although there is another message about AppleACPIPlatform right after and immediate dependencies.

I'm not sure how to proceed and need some help. Is there any way to fix this to get it to start installing SL?
