No Bootable Device

First of all thank you for reading this.

I have MacBook Pro mid 2012

I was using bootcamp and ceated windows 8.1 pro install disk after that I tried to install , partition was successful but after that i got ' no bootable disk'

I used option key after switching on and selected windows thumbnail the result was same and came to know about bootcamp drives .

I used bootcamp to download windows support drives with 1mbps speed it took 2 gb and going. I stopped it started bootcamp again with all three options selected create, download and install again result was same.

So thought of creating install disk and downloaded bootcamp drives from apple website and i am confused where to copy that in install disk.

Please help me and once again thank you for reading.

Please post back if you run into any issues after you are able to build the USB installer.


USB3 drivers do not exist on any Windows installer, so a USB2 should be used. USB3 drivers (IntelXHCI) is installed after Windows is installed and BC drivers are installed. The physical ports on a Mac which are USB3, also support USB2 devices without any issues.
