Q: iMac Retina 3tb fusion drive mishap

So, i tried to install bootcamp on my new Retina iMac without knowing the issues, and well, my machine is pretty much toast. I tired to fix the error using some of the terminal commands here, and when I try to reinstall Yosemite, it gives me no choices for start up disk, like it isn't there at all. DU shows I have all my space, but I can't write to it. Can someone please help????

Can you post the output of the following OS X Terminal command? If there is no OS X on the internal drive, you can use Internet Recovery (Command+Opt+R - reference OS X: About OS X Recovery - Apple Support).

diskutil list
diskutil cs list
sudo gpt -vv -r show /dev/disk0
sudo gpt -vv -r show /dev/disk1

The Recovery console does not need "sudo" before the commands.

You can also install OS X on an external disk - OS X: Installing OS X on an external volume - Apple Support and boot from it to diagnose/fix any issues.
