First post here guys and I have a question about my partitioned disk. A while ago I had windows installed but didn't use it much, so I went ahead and erased the disk using disk utility in hopes of expanding my Snow Leopard portion into that empty space. Unfortunately this didn't work as I planned so for a couple months I was stuck with half a hard drive. This wasn't a huge problem however it was annoying knowing I had a wasted chunk of HD space. I also had plans to upgrade to Mountain Lion, which I did today. I installed it in the empty portion of HD space so now I am running two OS's on my machine. I was hoping that once I copied some files and apps to my Lion partition, I could simply erase the bottom partition and then drag Lion into that empty space. Not sure if this will work or how to proceed, but I've attached a screenshot detailing my problem.
