Q: My Mac mini late 2012 won't boot: stuck at total black screen

So,

I tried to install Windows 8 with bootcamp using a USB. It didn't work ("cannot make a new partition on this disk or some **** like that") but this, I'm sure did not affect my OS X install, all I ever did was format the Bootcamp partition.

So, I exit the Windows installer, restart and remove the USB. Now I get the black screen that OSX shows when it has no OS, giving me the impression that it wiped / corrupted the install.

Fine...

But there's a twist. I can't hold option to get to the bootup device selector, neither can I press CMD + R or internet recover. Target wire doesn't work. I have reset the NVRAM successfully some times, but it still boots black.

I am using a wired keyboard, and mouse. I tried using a external SuperDrive with a CD. Same extent as USB. I'm lost, and I'm an experienced techie and I confess I am an iSheep. So yeah.

Thanks.

(And I haven't done any third party upgrades other than an SSD, which has worked fine for ages)

EDIT: and I reset the SMC EDIT 2: I also know that it probably isn't a hardware issue, I am positive my OS X install and OS X recovery partition are corrupted. I don't understand why I can't hold option, and I don't get why internet recovery doesn't work when you have no recovery partition. I'd be grateful if I could boot anything, without having to open up my Mac

Mac mini (Late 2012), OS X El Capitan (10.11.2)
