So today I decided to install ML. To do so I split my partition into two (the partition I was already using and another partition to install ML on) after this I installed ML into the blank partition I created with the intent to erase my old partition with Lion on it and add the free space from that to my new Mountain Lion partition. The only problem now is after I deleted the old Lion partition I don't know how to add the free space to my new (ML) partition. HELP?!?!
