Resize disk partitions

Here is my scenario:

Macbook Pro with the follwing partition on disk:

1 partition named Lion with 320GB

1 partition named Mavericks 114.6GB

1 partition named Snow 63.87GB

I want to increase the size of Mavericks, so I boot with Mavericks and using Disk Utility -> clicked on disk -> Partition -> and change the Lion partition value from 320GB to 128GB -> Apply.

Rebooted using Lion and using Disk Utility, have the size of Lion as 128GB, tried to resize the Mavericks from 114.6GB to 200GB, but, tapped TAB or clicking in apply nothing happens and the values comes back to 114.6GB

Already tried to reboot with command R and using disk utility repaired the disk that didn't find any errors.

What am I doing wrong?

MacBook Pro, OS X Mavericks (10.9)

Ah! The proverbial missing information. If none of those solve your problem, contact AppleCare.

In your situation, you can only resize the last partition, to a smaller size. You can't resize/move a partition's starting point, just its end point.

If you want to reduce the size of the 1st partition, apparently your Lion partition, you'll need to remove the last 2 partitions first. Then add the 2 partitions back. Needless to say, without having cloned backups of the last 2 partitions, it's not doable.

Assuming that you're using Disk Utility.

Yes, this is all that I found, It's only possible to change the end of the partition, NOT possible resize the begin of the partition. I was try so see somebody have different answer but seems that there is not "secret" to extend the begin of the partition (except clone, or ohter trirdy part utilities).

Thanks
