Failed Bootcamp - Unwanted partition

[Big Ron]

I tried to instal Win 10 via bootcamp but the installation failed. I'm not too bothered it failed however during the process Bootcamp made a 32Gbyte partition which I now can't delete.

I can see it in OSX and read/write to it with no problems however I don't want it there anymore.

Disk utility doesn't seem to be able to 'absorb' it back into my main drive.

How do I proceed?

If you open Boot Camp Assistant and try to create a partition again, does it prompt you to erase and restore the drive size?

Good Morning Alonso - thanks for the quick reply.
When I enter Boot Camp assistant I get the following pop up message.

"The startup disk cannot be partitioned or restored to a single partition. The startup disk must be formatted as a single Mac OS extended (Journaled) volume or already partitioned by Boot Camp Assistant for installing Windows"

Could you do me a favor and paste the following lines into Terminal.app for me, you may have to enter your password.

Please reply with the output from Terminal.app with all information it lists.

diskutil list
sudo gpt -vv -r show /dev/disk0
sudo fdisk /dev/disk0

Hi Alonso

Have you had chance to look at this some more?

Hi Alonso

Have you had chance to look at this some more?

*******
I would suggest the following but I am not an expert at all. So decide by yourself please.
This is what I would do, but, as already said, listen to people who know more.
So again, that would be my procedure if it was my computer, to get OSX to extend to the whole inner drive.
I would make a bootable clone of my OSX partition with for instance CarbonCopyCloner into an external USB drive.
Then I would boot from that clone and format (erase) my computer drive to one partition.
Then I would clone back my system from the external clone to the internal drive.
That would bring back the OSX partition to cover the entire computer drive.
***********+++
Now regarding how to do install Windows with BootCamp
I did not succeed with the BootCamp assistant coming with El Capitan.
I had to go around and around to install Windows.
I cloned my El Capitan to an external USB drive as mentioned above.
Then I booted from that external drive, erased El Capitan from the inner drive and installed into it a basic Yosemite, just the OS.
Using the BootCamp of Yosemite I succeeded to install Windows.
Finally I booted again from the USB drive, erased the Yosemite and cloned back El Capitan to the inner drive.
