Windows couldn't update the computer's boot configuration

Hello.


I have MacBook Pro 15" mid 2014 with latest OS X 10.10.3.

I've tried to install Windows with Boot Camp Assistant in many ways but nothing helps.

Tried to install Windows 8.1 and even Windows 10, more than 6 times and every time it fails on installation point "Finishing up".

Tried normal Boot Camp install, and every time i get this:

And when trying to do EFI boot, gives me this on the same installation point:

Thank you.

MacBook Pro with Retina display, OS X Yosemite (10.10.3), Mid 2014 MGXC2

If you switch between legacy and EFI boot, are you deleting the partition via BCA? If not, it can leave lingering MBR information, which causes problems. Your Mac supports EFI (it is UEFI compliant).


1. Reset SMC and NVRAM every time you try a new iteration.

a. Resetting the System Management Controller (SMC) on your Mac - Apple Support

b. How to Reset NVRAM on your Mac - Apple Support

2. For EFI boot, the simplest method is

a. Create a Free Space partition via Disk Utility.

b. Boot from Windows Installer (W7 has issues, W8+ work much better).

c. Install Windows in partition from step 2a.

d. Install BC drivers from a USB2 flash drive.

e. This method does not need BCA, but does need BC drivers, post installation.
