Good evening, everyone.
Late 2013 MacBook Pro with Retina Display
2.6GHz Quad-core Intel Core i7 (Crystalwell)
Intel Iris Pro 1024MB
NVIDIA GeForce GT 750M 2GB GDDR5
16GB 1600MHz DDR3L SDRAM
512GB Flash Storage
OS X 10.9 (13A3017) - Mavericks
A few days ago I installed Windows 8.1 from a bootable USB flash drive using Boot Camp Assistant [Version 5.1.1 (479)] and the .iso provided to me by the Microsoft Store on a 50GB partition. Everything worked flawlessly; Windows 8.1 installation, Apple drivers, Windows updates, wi-fi, Office 2013 installation, etc.
I soon decided that I would rather have my partition be approximately 100GB (128GB specifically) to allow me more space for when I am in the native Windows environment. Using Boot Camp Assistant, I erased the Windows 8.1 partition and created a new 128GB partition. Installation process was proceeding the same way as the first time, but I received the following error message when the installation was finalizing: "Windows could not update the computer's boot configuration. Installation cannot proceed." and "The installation was cancelled. Any changes made to your computer won't be saved."
I then decided to start from scratch. I reformatted my USB flash drive and used Boot Camp Assistant to reconfigure the bootable USB flash drive using the Windows 8.1 .iso. I also erased the Windows partition using Boot Camp Assistant and recreated it with 128GB. Unfortunately, I was stopped at the same point in the Windows 8.1 installation process with the same error messages.
This is a bit vexing to me as the only change in the process I have made from the successful Windows 8.1 installation is the amount of space I allotted on the Windows partition (50GB to 128GB). Could this actually be the issue?
I have read around a bit on this error message and it appears to be a common reply that this version of Boot Camp Assistant does not support Windows 8.1. I can say with absolute certainty that statement is untrue as I have successfully used it for this purpose already.
I greatly appreciate your collective knowledge and assistance. Thank you in advance.
