Okay, hi all.
I have also a K50IN, and I will install Snow Leopard on my notebook.

I have only 1 problem. I have no PC or Notebook with OS X, but my friend has, so I will create my installer USB on his Mac.
But can I boot my installer here in my K50IN, because I've read somethings about DSDT that will be created if you make a installer with the guide (from flip's first post).

Guys, can you help me ?
