Problems setting up dual boot

I am trying to set-up dual boot with Vista and OSX 10.5.1 both are installed but while following the instruction to change the MBR using EasyBCD 1.7.1 i get to adding the mac record I can select Generic x86 PC but then it says to click automatic configuration and i just dont get that option. I tried to reinstall EasyBCD and that didnt seem to change anything. Any help I could get would be greatly welcome.
Now i am getting the HFS+ Partition Error abd when i try to use the utility in EasyBCD it doesnt seem to do anything. I have the partition on drive 0 part 1 and select that but it doesnt seem to do anything ie fix the error.
