I've just installed Leopard, but now I'm having some problems getting it to boot.

Before installing, I reinstalled Vista and moved some things around, so my HDD setup is now as below:
HDD1: (200gb)
Partition 1: Vista
Partition 2: Storage

HDD2: (80gb)
Trying to install Leo here

(I have unplugged HDD1 and still is unplugged). When I installed, I use the 'Erase' function in the Disk Utility to Erase the whole drive to MacOS Extended (HFS+). I then installed the EFIv8 files, and unselected Additional Fonts and Languages and let the installer do its thing.
Then when I tried to boot into Leopard, I got the error:
"HFS+ Partition Error"
When I tried booting with the DVD, I got:
"System config file '/com.apple.Boot.plist' not found"

I tried the 'Making Mac Bootable' instructions from the Known-Issues wiki, and now when booting without the DVD I get:
"B0 Error"
And the same error as before if I boot with the DVD.

Does anyone know whats wrong? I'm going to now to installing Leopard again, so I'll post back if it works or I get errors again.
