Q: MacBook Pro not booting after Windows 10 boot camp

Hi,

There is a problem with my MacBook Pro (Retina, 15-inch, Mid 2014).

I have updated OS X to macOS Sierra (version 10.12), restarted MacBook Pro and did the clean installation of macOS using Recovery manager (Cmd+R on booting).

Next I have created the boot camp installation USB flash drive using ISO file of Windows 10 Pro x64 Version 1607 and made Windows partition using Disk Utility.

And after that I have restarted MacBook Pro holding Option key and selected UEFI-boot from prepared USB-drive.

Installed Windows 10 Pro x64 on the prepared Windows partition. After successful installation MacBook Pro restarted and I heard standard chime and black screen with back light appeared, no booting to Windows or macOS, no options.

I turned it off and turned on again. Tried to hold Option key, Cmd+R, C, D. Nothing.

Also I reset SMC and PRAM. But nothing changed. There are only chime and black screen with back light.

Could you please help me? What could happen? Thanks.

Specifications of MacBook Pro:

MacBook Pro (Retina, 15-inch, Mid 2014)

2.5GHz quad-core Intel Core i7 processor

16GB of 1600MHz DDR3L onboard memory

512GB PCIe-based flash storage

If you boot and hold the Alt/Option key, what are the available selections in Boot Manager?

Please use How to install OS X on an external drive connected to your Mac - Apple Support to install OSX on an external disk and upgrade, if necessary, to match the internal disk OSX version. Once it matches, boot from the external disk and we can look at your internal disk to diagnose further.

Thank you for your advice. I have installed OSX to my external HDD USB 3.0 drive. I have connected this external drive to my MacBook Pro. But how can I boot from this drive?

Boot into Local Recovery and connect your external USB HDD. If you click on the Apple icon and Quit, you should see a dialog to choose your startup disk. Choose the external USB HDD as the Startup Disk.

Can you verify that your NVRAM Reset followed the steps in How to Reset NVRAM on your Mac - Apple Support ?

If your internal disk was converted to MBR, then internal OS X will not boot, external USB HDD should be GPT and boot.

How did you install OS X on the external USB3 HDD, if your Local and Internet Recovery do not work on this Mac? Do you have a second Mac?

Also, if you boot and hold the T key, do you see a floating firewire/thunderbolt icon?
