A lot of people are experiencing the same error. Interestingly enough, it is not an error. I encountered the same thing, and this is what I did.

heres the deal, Make sure your partition is configured with MBR (Master Boot Record), and assure that the name of your Partition/HD Volume is one word only, i.e. Leopard, not Macintosh HD.

Lastly, make sure the Bootloader you install is MBR as well.

You should be on the road then. - WinLinMac01
