Hi mate, no problem!

It's important to know though, because in order to install the bootloader properly, you will need to know that Information!

MBR or GUID
With EFI or without EFI

Please navigate to Utilites and start the Disk Utility, choose your Leopard Harddrive and press Info, now check whether it's MBR or GUID.

If you have that information, you will be able to go ahead and install the bootloader manually, I will tell you how to do it.
