Q: No sound after installing Windows 10 on Boot Camp

Hi Eduardo, everyone, thanks first for this feed.

Did it work? If yes, did this help you anyhow?

Thanks

Hi Loner T., everyone, thanks for the feed,

Is a mid-2011 13' Macbook Pro suitable for Win10 BCA's through this?

I'm having the sound problem on Win10 (Code 10). I'm UEFI.

Facing the GPT v MBR problem I installed through a bootable 8.1 DVD (USB external SuperDrive as SSD extended), a bunch of DISKPART commands, an upgrade to 10 and a manual setup of some of the Bootcamp 5.1.5640 drivers as I was unable to follow the BCA process.

Aside from the GPT problem I got everything from the 'won't-let-you-create-a-bootable-pendrive', the 'won't-boot-on-install-if-not-pressing-alt', the 'black-screen-blinking-prompt', the 'no-bootable-device' to the classic 'frozen-please-press-any-key' before.

I changed OS (tried from El Capitan, Lion & Yosemite), did the info.plist twist (exluding the further steps detailed in the link you provided), nothing worked. I now understand I need to re-install Win10 with proper BCA steps but as far as you know is it possible on a mid-2011 13' MacBook Pro?

Thanks again.

Does your built-in Optical drive work? The 2011 MBPs are not officially supported, but in most cases, W10 will work. You will need to install on a disk which has a Hybrid MBR which bridges the GPT to a MBR.

I removed the build-in, replaced by a SSD drive and made a it a USB external optical drive. It worked installing Win8.1.

I'll check on how formating my drive in a Hybrid MBR and revert.

Thanks for the quick reply Loner.

Temporarily, put the Optical drive in it's original location. Out the designated drive for Windows in main bay, and install Windows normally, then replace the Optibay drive with the drive of your choice and test.

Ok, I understand I may be a bit late to the party, but I had just solved the same problem with Windows 10. Now I am writing this under my Windows 10 account, while listening to Aristocrats Radio =)

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.
