windows installer not booting up after resizing the partition

Hello.

I am trying to reinstalling Windows 8.1. pro on my macbook with Yosemite.

When I initially installed Windows, it went fine, but Windows corrupted my booting process.

So I tried to fix it with gdisk command to create hybrid mbr, but I was not able to fix the problem.

So I deleted the Boot Camp partition using Boot Camp Assistant.

then I created a new Boot Camp partition through Boot Camp Assistant.

However, Windows installer did not boot up automatically nor manually(pressing option whilst booting) anymore.

I have booted up Windows installer using the same usb on pc, so I know that the usb containing Windows installer does work..

I am not sure how to boot the Windows installer.

Do I have to do clean install the OS X??

thank you for your help and time in advance.

Rin

MacBook Pro with Retina display, OS X Yosemite (10.10.2)

Was the USB created using BC Assistant? Is it a USB2 disk?

Hi, Loner T

Thank you for your response again.

It was bootable USB stick that I created on the PC.

That had also worked OK last time.

Each time when I tried to boot USB stick from the screen pressing option, the Mac freeze.

Is it possible to create the disk using BCA and a Windows ISO on the Mac, if your Mac supports it? If your Mac has a built-in Optical drive (or used to have one), you are going to run into issues.

Can you

1. Run Disk Utility Repair.

2. SMC Reset - Intel-based Macs: Resetting the System Management Controller (SMC) - Apple Support

3. PRAM Reset - OS X Yosemite: Reset your computer’s PRAM
