So two days ago I partitioned my HD on my MBP for windows vista and didn't like it much so I unpartitioned it back to all Leopard. Now when I turn on my notebook it goes to a black screen saying "no bootable drive found please press any key to reboot." or something like that. It doesn't start up as leopard like its supposed to. Now I have to hold the option key every time to manually start leopard. But the wierd thing is that every time i hold the option key Mac HD is the only thing i can select so I know windows is gone but it doesn't recgonize that leopard is the main start up OS? Help?!?!
