I have installed Windows 8.1 in Macbook pro and after installation, audio driver doesn't seem to load. It gives error 10 saying Audio device is not installed.
MacBook Pro
Was Windows installed using EFI Boot? What year/model is your Mac?
I tried using bootcamp but during installation accidentally I wiped out "all my drive" and I have to say it's clean fresh only Windows installation 😟.
My device is Macbook Pro, 2012/13 build, had OS Lion 10.7.
Is there any way to fix it or restore Lion or install Yosemite?
Did you insert a W8 DVD in the Mac and directly boot from it without BCA partitioning? Can you run Internet Recovery Command+Opt+R during power up?
Please see OS X: About OS X Recovery - Apple Support and make sure you look at the OS X version(s) that it may offer.
