Trying to salvage my Windows install

System specs:
Asus Maximus VII Gene
Intel Core i5-4690k
Corsair Dominator Platinum 8GB
2x Samsung 840 EVO 250GB
no graphics card installed

Hey all,

I've been trying for the past few hours to get Yosemite running on my computer. I successfully set up a Hackintosh back around 2010/2011 (I think using Uni/Multibeast), so I had some sense of what I was doing, and I really wanted to try out Yosemite.

I pulled an 840 EVO from my HTPC for the install specifically for the purpose of leaving my Windows drive alone. I started out trying Clover but it seemed way more complicated than I was comfortable with, so I switched over to Tonymac's guide using Uni/Multibeast.

The first time I booted (from USB) I got an error that was remedied by booting with -v and -x. I formatted the SSD per the instructions, installed, and booted into Yosemite. Lo and behold, everything was working perfectly. Keyboard, mouse, and LAN all worked on boot without me touching anything. Audio didn't work but I didn't expect it to because the Gene has a custom card from Asus.

So I ran Multibeast, selected DSDT-free. I left all drivers unchecked. I enabled a few things in the Customize section (that I maybe shouldn't have?) I rebooted and nothing worked anymore, not my keyboard, mouse or LAN. (Safari launched on boot and couldn't connect to network) I also noticed some weird graphical glitches at certain moments during the login process.

No problem. I messed around with it for a good while before I ran Multibeast so I checked out what I wanted to check out for the most part. Unfortunately, when I try to boot into Windows from Chimera or Chameleon or whatever I am getting an error:

File: BootBcd
Status: 0xc000000e
Info: The Boot Configuration Data for your PC is missing or contains errors.

I've tried some stuff mentioned in this thread: http://www.tonymacx86.com/windows/82521-error-while-booting-windows-dual-boot-separate-drives.html

like disabling the Mac install drive in the BIOS and forcing it to boot from the Windnows drive, but that results in a black screen for a few seconds before returning me to BIOS. Any ideas? I'm preparing a recovery USB disk now to try and repair the bootloader but I have a feeling it's not going to work

remove the OS X drive and boot with the Win8 drive. If you disabled secure bot in BIOS to install OS X, enable it again.

Isn't that the same thing as disablng the whole SATA lane for the drive in the BIOS? If I do that and then force boot from my Windows drive nothing happens. I just get returned to my BIOS after a few seconds of black screen. Either way I will try to physically remove it and report back with my results.

Secure Boot is enabled.

EDIT:
Physically removing the drive did not change my results. Also repairing the bootloader with a recovery disk did not work. I no longer get the error, just a boot loop.

Thanks for the help, but at this point I need a working computer so I'm just gonna grab any files I didn't backup from my Windows drive and re-install.

With Windows installed Secure boot and you deleted some files & booting with the install DVD and repairing the boot sector doesn't work, re-install with Secure Boot disabled. Secure boot must be disabled to run OS X or Secure Boot must be set to Other OS if you have that setting and can't disable totally.
