Hi there megaargon, i got past this issue by using the make bootable hd for leopard cd before i installed leopard.its on the web somewhere (google is your friend here). sadly though it does mean starting again (unless anybody here knows another way). Dual booting with xp or vista is easy too (just use separate hd and disconnect macosx before you do install, then use easybcd 1.5.1 in xp or vista to add osx to bootloader) its a pretty easy setup and also works with triple boot just install vista last and disconnect macosx on vista install..

Hope this info helps, i will be around if you need any further help..
