I am trying to partition my internal hard drive to install Linux Mint. However, when I go to the partition tab, the "+" symbol and all other options are greyed out. I had tried to install Linux a a year ago and had partitioned the disk. But i removed that partition. The partitions that are visible to me are Macintosh HD, Recovery HD and an old partition that is in Mac OS Extended. That is there are 3 partitions in all.
I would be grateful for any help! Thanks!
