Hi fellow mac users!

So I heard it recommended that I should create a new partition to try El Capitan. I have done this, and it has installed successfully. However, now I am left with two problems

I can't get El Capitan on my original partition as it says it has already been installed.

I can't reverse the process of partitioning, so I am now stuck with two partitions on my computer.

Please help!

I don't understand your first question.
You can always remove partitions from Disk Utility.

This time it won't give me the option. There is a plus and a minus button, and when I try to click the minus button, nothing happens.

Are you booted from the partition you are trying to remove?

You can download the El Capitan installer again in App Store under Purchases.

It sounds like perhaps the El Capitan install converted the volume to a core storage volume that cannot be manipulate normally in Disk Utility.

Run the command below in Terminal and post the output up here so we can have a look.

Code:
diskutil cs list
