Can't resize shrunken boot partition to fill empty space I needed to make room on my Windows 7 partition to install a new program, so I did some searching on how to resize a partition and it told me to shrink the OSX side and then expand the Windows one into the free space from Windows.  

That didn't work, so now I have a 245 GB boot partition (my main OSX one), then roughly 10 GB of free space, then a ~61 GB Windows partition.

I tried to just drag the corner down on the OSX partition and click apply, but all it does is unmount and re-mount Windows 7 without changing anything.

I don't really care whether I expand the Windows partition into the free space as I originally intended or just re-expand the Lion one into that dead space, but there's about 12 GB of space there that's not doing anything, and I'd like to use it.

Any ideas?
First, try to delete the Bootcamp partition using Boot Camp Assistant.
I had a similar problem, and Boot Camp Assistant didn't recognize any Bootcamp/Windows partition, but in Disk Utility, the size of total space of my 1 TB HD showed only 850 GB of total space. The other 150 GB (from a failed attempt to create a bootcamp partition) did not show in the Disk Utility or anywhere else.

Then, quite by accident, I created 2 additional partitions using the Disk Utility.  The total space of the 3 partitions showed as 850 GB. However, I then used the Disk Utility to delete the 2 additional partitions which I had created, and it allowed me to specify a resized single partition of 1 TB.  After I had deleted the 2 additional partitions and resized to a single 1 TB partition, the total available space showed up as 1 TB (or actually, 999.97 GB), which seems as though I recovered all of the unused drive space.  :)
