Hey everybody,
I really need your help.
Here's the problem. I made three partitions in addition to my main Mac HD when I was trying to install Ubuntu (which failed). As a result of Ubuntu's failure, I tried to remove the partitions. Unfortunately, I could not. I've tried Disk Utility, but whenever I want to remove a partition, it just gets stuck on "Preparing to Remove Volume." In addition, one of the partitions can't be mounted and can't be erased because there's always an error.
Bootcamp won't work either because whenever I try it gives me a message saying "The startup disk cannot be partitioned or restored to a single partition."
I really need your help, and if there are any suggestions, I'd really prefer cost-free methods.
