Kali Linux on Macbook A1181

Hello world,

I've some problems while installing the Kali-Linux image on a Macbook A1181.
Even when the system boot's up the following text appears:

GRUB loading .
Welcome to GRUB!

error: unknown filesystem.
Entering rescue mode...
grub rescue> _

Every time I've installed the image the same errror encured and i can't even write sth. down.
Booting from USB isn't available at the A1181 and the Live-Distribution is'nt available on my Kali-DVD.

If someone could help me i would be very thankfull.
