    I have 60GB of free space from a partition I deleted. I want to remove it so that my main partition will use up all the space. When I do so I get the error "You can’t perform this resize unless it has a booter". A screenshot is attached.[​IMG]

    The Yosemite install turned your drive into a core storage volume and that is why you cannot resize. Disconnect any other drives, then run the command below in Terminal to turn off the core storage then you should be able to resize.

    Code:
    diskutil cs revert /

    This is what I got "Started CoreStorage operation on disk1 Macintosh HD
    Error: -69741: The target disk isn't eligible for reversion because it wasn't created by conversion or it is not part of a simple setup of exactly one logical and one physical volume"

    Hmmm... do you happen to have Filevault2 encryption turned on?

    Run the command below and post up the output.

    Code:
    diskutil cs list

    I had it on before but turned it off. The other partition was for Ubuntu and formatted in ext4 but I deleted by booting up Ubuntu from a usb drive and deleting it. The space is now registered as free space. Anyways here is the output.

    Here is the problem. However you did all this, it has left you with a core storage volume that cannot be reverted. So you will need to erase the drive and start over.

    Make a Time Machine backup to an external drive, then option key boot to that drive.

    From the recovery screen that comes up, go to the Utilities menu and start Terminal and enter the command below exactly like I have it, including the quotes. That will wipe the drive. Now quit Terminal and use Disk Util to erase the drive to Mac OS Extended (Journaled). Then quit Disk Util and click restore.

    That will put the OS and everything back and you should be in good shape.

    I'm going off line in a few, so if you get hung up, shoot me a PM and I'll jump back on. :)

    Code:
    diskutil cs delete "Macintosh HD"

    (this is just for info : there is another (not simpler) way. It's using.... Filevault. If you turn on Filevault, wait for the completion, then turn it off, the Core Storage will be deleted and the disk will be reverted to HFS+)

    You may not need to re-install. This worked for me after I had the same issue after removing Arch linux - the "The not-as-long-as-expected way" answer in http://apple.stackexchange.com/questions/154964/resizing-or-expanding-a-corestorage-volume

    For you the terminal command would be diskutil cs resizeStack 2FF08A1A-984C-4B06-B321-E3F00E88E5B7 0g when booted from external drive or in internet recovery mode.

    The link describes backing up the recovery partition and other steps but for me this command alone worked fine and just moved the recovery partition to the end of the disk.
