So i was going to do a duel boot, where i can boot leopard, and tiger at the same time.. during leopard install i accidentally erased everything on my original tiger drive and installed leopard on one my hd along with another HD partition that's not being used. what i wanna do is delete the partition that has 80 gb on it (nothing) and move that 80 gb to my leopard partition. only problem is, after i deleted the partition that had nothing on it. i cannot move the slider.. and when i go to 1 partition instead of 2, it says it will erase everything on my main OS.. so how do i get my free space back on my leopard drive? i hope this isnt that confusing..
