Hi,

I need to disable the "High Definition Audio Device" which, despite me having uninstalled it from Device Manager multiple times, reappears after every reboot.

I did a little Googling and found rEFInd...

Naturally I'm a little hesitant to use it. If I made a mistake in EFI, how do I rectify it? Is there some way to reset the EFI?
 
rEFInd is an awesome program and the programmer is very helpful. You won't have any serious issues and it's easy to bypass if something were to go wrong. Good luck.

I see. Thanks for your reply.

Does resetting PRAM, etc., reset the EFI to its default state?

Yes, if you reset PRAM rEFInd no longer boots and you fall back to the default OSX loader.

Don't be hesitant - it is an excellent bootloader and despite rather intimidating documentation extremely easy to use. There were some complications with Yosemite due to LVM but these were fixed earlier this year (it now installs by default to ESP). All you need to do is download the latest version and type ./install.sh

Only when dual booting Arch have I had to change the default script to pass different parameters - everything else has worked fine out of the box.
