Adding more storage and dual booting.

My Problem

I needed more memory and my disk drive was already busted plus i don't use it anyway so its just easier to throw a Wd blue 1 TB 2.5 drive in its place.

My Fix

The drive swap went great installing windows 8.1 for dual booting (with el captain) went well but the High Definition audio controller fails to start and no sound devices are recognized as installed, tried all solutions to no avail, only thing that works is usb headphones.

My Advice

Might be a great time to clean out your fan!
