Can't resize partition after deleting old one

[Chris354354]

To downgrade from Lion back to snow leopard on my macbook I created a new partition, installed snow leopard on it, deleted my lion partition, but now I cant resize the snow leopard to full.

I haven't played with extending partitions on OS X, but I do know on the systems I've done that, it required the free to be adjacent to the end of the partition and not the start of it.

So the probable solution is to create a partition using the free space and cloning your installation to it and after that is working delete the partition at the end of the disk and then try extending your partition.

I have resized in OS X, and I think you are correct. I have always resized the one on top with blank space on the bottom like in this article. I believe the boot partition is always first, and OP booted to another partition then deleted what was the boot partition and wonked things up.
