Q: SuperDrive broken cannot Boot Camp Windows to El Capitan

I have tried many schemes suggested in this forum and at least a dozen different ways to get El Capitan to boot camp Windows. I've run csrutil disable from recovery, and used the gdisk utility to rewrite the drive map to use GPT.  I seem to get as far as installing all the Windows 10 files then I get the Windows message "Windows could not prepare the computer to boot into the next phase of installation. To install Windows, restart the installation." I've tried bcdboot c:\windows and manually entering the drive and also partition GUIDs I recorded from gdisk detail option. But I get errors co so there is something still not executing.

 

I have not yet tried Rufus. I used unetbootin to make my Windows 10 flash drive from the microsoft 64-bit ISO. I also have an OEM Windows 8 disc purchased three years ago. I'm a bit concerned about barking up multiple trees simultaneously.

 

It's a MacBookPro6,1 EFI and SMC confirmed current. 8GB Crucial RAM. The SuperDrive does not function, nor will my USB Pioneer BD-204 burner (with confirmed latest firmware, which effectively turns it into a BD-205) allow installation of Windows despite offering an optical EFI partition after option-reboot. I've been able to get Windows installed from a USB drive I made from a downloaded ISO from Microsoft Using unetbootin as described. Maybe Rufus solves this issue?

 

I'm fully prepared to scrub the entire drive (which I actually had done yesterday, by a Genius) and start from scratch if I just could find a step-by that would actually work. I really need to boot camp Windows 8 or 10 onto this machine again.

 

I am even prepared to install another internal drive in place of the SuperDrive to boot camp Windows, but I want to make sure I won't run into the exact same issues if I take that step.

 

Also boot camp simply does not offer me the option to specify an ISO, there's only two not three checkboxes, and every time I try from the disc, I get the black "system unboot press a key" lockup after it restarts.

 

I have also edited boot camp's info.plist to add my model to the 32-bit models list.

 

There are absolutely no backup issues etc., the Genius yesterday was so smart he told me to try a Microsoft store.

 

Please help this is going on 10 days I've been trying to solve this now. Should I go back to the Apple Store and ask them to put Mavericks on it? That's how I got Windows 8.1 boot camped three years ago.

MacBook Pro, OS X El Capitan (10.11.6), SuperDrive blocks discs, 8GB RAM
