    I can't seem to click the "-" (minus) button in Disk Utility to delete this second partition. I have tried in recovery mode, and tried ejecting the partition, but no joy. What am I missing?

    Easy fix

    I know this is an old article, but this recently happened to me and the easiest way to get rid of the Yosemite partition is to:

    1) Boot your other OS, mine was Mavericks
    2) Open Disk Utility
    3) Select the Yosemite partition
    4) Select the erase tab, erase it
    5) Select the main drive and go to the partition tab, where you can then delete the Yosemite partition and resize it back to the original size.

    Hope that helps!
