Windows still shows up on boot even after I deleted bootcamp partition

Hi,


El Capitan just came out, so I made a fresh install. I deleted all my partitions (OS X and Bootcamp) in the Disk Utility, then made a fresh El Capitan install.

My problem is that when I press the alt key on boot, the Windows option still shows up, but I no longer have the bootcamp partition since I deleted it, because I no longer need windows.


I tried choosing the windows option on boot to see what happens and it obviously goes into a blue screen repair mode (not a surprise since I deleted the entire partition).


Is there any way to somehow remove Windows completely so it will no longer offer it as an option when I press alt during the boot? And to make sure there is not even a single byte stored on my computer that is related to windows.


Thank you

iMac with Retina 5K display, OS X El Capitan (10.11)

The external disk can have windows stuff on it since I use it to run windows.

What I want to avoid is to have any windows remainings on my internal disk because I used bootcamp in the past.

This is the output:

I did erase the whole disk before I installed a clean El Capitan and I still see Windows as an option when I press alt...
