Mac OSx86 (iDeneb) does not boot

[EdeBoi]

Ok, mates, i got an problem:
i installed on the second partition of my Harddisk iDeneb 1.4 (on the other is WinXP Pro SP3)

I installed, everything worked fine.
But after the reboot, i get this screen:


the dvd drive is not spinning anymore, but the light is flashing, also my Harddrive does not work.

What could it be?
Could it be because of Windows xp and the MBR?

How can i fix it?
