was the 20GB second partition used for a Boot Camp Windows Install before ?
No.
Have you tried, while running Leopard to simply reformat the 20GB partition with the 'Mac OSX Extended (Jornaled)' file system ?
Running Leopard, Disk Utility shows that it +is now+ formatted to Mac OS Extended (Journaled).
When you boot from the Tiger DVD can you access the Disk Utility (from the Top Menu - Utilities) and check if the 20GB partition is shown ?
Yes, it is.
It seems to me that the "Install Mac OS X" program on the grey DVD that comes with the Mini, unlike the one on the black DVD that you buy separately for $129 USD, lacks the function that asks you what partition you want to install it on. When you have one empty partition, it chooses the Wrong One (for me) and wants to reinstall over the partition that already has a system. So I wonder which one it chooses if you have, say, two empty partitions?
