Hey I know this is an age old question that has been answered many a time but I'm still hang issues with it. I've throughly searched the web and found a few different solutions to cases similar to mine but I can't seem to get this thing working so here it goes: Once upon a time I thought Ubuntu was cool so I partitioned a small part of my hard drive to allow for this. Well now I want to free up space on my mac by deleting the partition. Here's where the problems occur. The first thing I tried was the Boot Camp Assistant to restore my hard drive but when I try to do this I get the following error: The startup disk cannot be partitioned or restored to a single partition. The startup disk must be formatted as a single Mac OS Extended (Journaled) volume or already partitioned by Boot Camp Assistant for installing Windows. Since the Boot Camp Assistant couldn't help me I decided to try the Disk Utility. On the left side of the screen I selected Fujitsu mhy2250bh media and then clicked partition on the right. Well for whatever reason I now see 3 partitions: BOOTCAMP, disk0s5, and Linux Swap. I have no idea where disk0s5 or Linux Swap came from so they're really bothering me and I want them gone. When I click the partition and then select the "-" symbol to remove the volume the status bar does flashes and says "preparing to remove volume" and continues to do this until I have to force quit the disk utility. I have tried everything I can think of but I still can't delete these damn partitions. Any ideas?
