Currently Being ModeratedOct 21, 2008 4:51 PM (in response to AndrewCapon)it can see all 4 hard disks and ntfs/fat partitions on three of the disks.
1. I suggest you disconnect all your drives and see if you can boot from your Leopard DVD. If you can, the 'no boot' issues is obviously being caused by one of the drives. If this is the case, I would try to identify which drive, by connecting just one of them and trying to boot from the OS DVD. Then do the same thing with another drive, and so on. If you are lucky, you should be able, by trial and error, to isolate the drive (or drives) that are the problem.
2. It does seem that you already have a clue that the system disk is the culprit. You could just disconnect that one and try booting from your OS DVD.

Thanks for the replies.
I have changed the video card back to the original one and I can now boot the install disk.
Thanks very much for the help you have saved me a long winded call to applecare.
All the best
