[biohazard6969]

i opened up my macbook, and it wouldn't wake up i did a restart by holding down the power button and it restarted while i held option but in the screen that came up it only showed the one windows partition and there is no option for os x partition. i don't think i've done anythign wrong. i need to know wats going on

 

[crees!]

You could try popping in the OS X install disk and running Disk Utility. See if the OS X partition shows and if it does try a repair disk on it.
