iPC 10.5.6 Final only starts sometimes....

[eskild12]

Hey I have installed iPC 10.5.6 final and everything works well except that the pc only starts sometimes. I can get it to boot 100% if i first boot in windows and then restart and boot in mac then it always work but i don't wanna do that everytime. What happens when i boot in mac is that it will stay at black screen with a cursor in the corner and i can't move the mouse.
I have no idea why it only works sometimes.


Thanks for all help
