I don't know if this has been asked i've tried looking around but can't seem to find it so i just decided to ask. I'm trying to get mac osx (of course) on my pc but it doesn't seem to work correctly heres what i got

HP Pavilion dv6000
intel duo core 2
nvidia 8400 gs

i am trying to pull this off from an external HD the install has been successful but when it tries to run i keep getting a dark grey screen saying to "restart my computer by pressing the power button" i've done this servral times but still keep getting the same thing any ideas?
