No Audio ( Bootcamp )

Is it possible to

1. Move the designated Windows drive to the main bay of the Mac, and,

2. Re-install the Optical drive to get Windows installed.

Once Windows is installed, replace the optical bay/drive with your non-Windows drive.

Is this the only solution?

If done this way, could I re-install the SSD into the main had drive bay, and then removing the optical drive again and replacing it with the original HDD that would now have windows install on it?

But why? That is the question that never gets answered --- The response 'just re-install using BOOTCAMP' is a solution but doesn't answer/explore the issue at all. I really want Apple to chirp up about it- I send them an email a week essentially asking the same question over and over again to no avail (I will keep trying though).

The reason why I reject the 'EFI Boot' issue is because I, like many others, run various linux distributions in pure EFI mode and all devices work, are seen etc.... This is even true with FreeBSD 10. So if the open source community, with far less resources mind you, can figure it out ; why let Apple and Microsoft off the hook.

I just want an explanation why. Yes, it is clear that EFI boot without the CSM layer of bios emulation is part of the issue ---but why? Why does linux do fine, why does FreeBSD do fine --- Those OS's see the Intel PCI audio bridge (device 27 on PCI 0) and the cirrus codecs and the various inputs and outputs out of the box!

So why ? Not an answer saying we should of used BOOTCAMP

The primary issue is related to device probes to query the EFI layer. OSes that support EFI do not rely on CSM-BIOS at all. FreeBSD or Linux distributions are primary examples of such. For Windows, installed in EFI Mode, the device probes do not collect embedded device information, and rely on CSM-BIOS.

On Macs from 2013 onwards, EFI and CSM-BIOS behave the same, so an OS can be installed using either. Legacy BIOS is still tied to an MBR from a partitioning perspective and has other limitations. 2012 Macs are an interesting implementation of preUEFI model, because they can install W10 in UEFI.

Try running MSinfo32 on a 2010 Mac with an EFI Windows and you will see a significant set of devices missing. Despite all this, Macs with EFI 1.1 on the OSX side work perfectly as do many Open source OS variants. Does that help?

Ok, I understand I may be a bit late to the party, but I had just solved the audio problem with Windows 10.

I copy my answer here from another similar thread.

I have a MacBook Pro 13" (mid-2012), 500 GB SSD and 16 GB RAM.

This issue boils down to a poor EFI support on older MacBooks. Boot Camp assumes it can do just fine with this, when creating a USB installer and partitioning the hard drive. However, EFI boot mode exposes devices in a different way, which effectively leads to audio not working.

Basically, the solution is to use a legacy MBR boot mode, when installing Windows. However, due to Boot Camp's tricky partitioning of a hard drive, legacy mode will not allow Windows installation to that partition (the infamous message "Windows cannot be installed. The selected disk is of GPT partition style" etc.).

To install Windows 10 without any of these problems, I did the following:

0. Saved the latest Windows drivers to a USB stick via Boot Camp.

1. Burned a Win10 ISO image to a DVD.

2. Merged a Boot Camp-created partition back to a single MacOS partition (did that via Boot Camp).

3. Created a new partition for Windows 10 in a Disk Utility (I assigned 100 GB, formatted to FAT).

4. Re-formatted this new partition to NTFS, using a third-party software. I used Tuxera NTFS for Mac (http://www.tuxera.com/products/tuxera-ntfs-for-mac/). It has a 15-day free trial.

5. Put my fresh Win10 DVD to an optical drive and rebooted, while holding Option key (alt).

6. In a boot options screen, I selected DVD "Windows" (Do not choose EFI boot.). Windows installation started.

7. In a Windows Installer Disk selector screen, I chose to install Windows to that NTFS partition created earlier.

It all went smoothly afterwards. Windows reboots a few times during installation process, as usual. In these cases please hold Option key during reboot, and then select to boot from hard drive "Windows".

After Windows is installed, do not forget to install latest Windows drivers from your USB stick.

NB: Before all that, I also played a bit with marking my MBR partition from hybrid to protected (see here: http://fgimian.github.io/blog/2016/03/12/installing-windows-10-on-a-mac-without- bootcamp/). However, I am not sure this actually was important in my case.

Hey Andrii, I have an early 2011 MacBook Pro 13, but have replaced the DVD drive with a second hard-drive.

Could this technique work for me?

Obviously, I could plug-in the DVD drive via USB; although this doesn't always behaved in the same fashion as when it's internal.

Thanks

No. Re-connect the Optical drive internally back to the Mac, and install using the Optical drive and physical DVD. Once Windows is installed, connect the second drive in the Optibay. Do not move the Windows drive to the Optibay. Windows is very unstable and crashes very frequently.

Uninstall Windows which was installed using EFI boot after you backup your important files. Install Windows using BCA and do not use EFI boot.

On the 2011 Macs, EFI layer does not expose the embedded Audio devices properly. Do you still have the original Optical drive that you took out from the Mac?

Yes, I purchased a superslim optical enclosure to put the optical drive in.

You can move the Windows disk to the Optibay, but it may cause issues with Windows booting.
