Everything works except the sound and internet.
Even connected ethernet straight to laptop doesn't work for some reason. I already know my internal wifi card is unsupported but i think i can get my belkin F5D7050 to work.

i was also wondering how to get it back dual booted with windows 7 that i had before

I cannot find how to get my audio to work though. if anybody knows I would be very thankful.
