No Sound after installing windows 10 on MBP 2012

Hi Everyone,

Here is what I have done.

I have MBP 2012 with El Capitan on it.

I have installed windows 10 on it. Below are the steps that i followed.

Changed Plist file to enable windows 10 iso creation on USB for my MBP (PreUSBBoot to USBBoot and 2 other usual changes)
Installed Windows 10 ISO file
Made a bootable USB though Bootcamp with drivers
Used disk utility to partition the drive for windows (Reason - as it gave error while installing windows, EFI MBR windows only on GPT device Error)
Restarted my MBP used option key and selected EFI boot (as while installing windows from Bootcamp it gave an error saying no bootable device found)
Installed Windows and loaded Driver through bootcamp setup
Everything works fine but the sound

Tried but failed

Clean installing of windows though bootcamp partition (error - no bootable device found)
EFI Boot (Error - EFI MBR GPT error, windows can be installed only on GPT Error)
Tried updating drivers for sound. However, did not work

Please help me with steps to resolve this. Also, the windows is not activated is there anyway through which i can still get windows 10 for free.

MacBook Pro

Modifying Info.plist is incorrect. Your 2012 MBP supports both, USB and DVD installations. Please use BCA and remove the current installation. Installing Windows using EFI Boot on a preUEFI machine will cause more problems.

Hi Loner T,

Thanks for your reply

I did modify P.list as there was no option available for me to make bootable usb from Windows ISO in bootcamp.

Do you suggest to overwrite p.list with the default file and then try to install windows once again from the Bootable USB through Bootcamp. If yes, I hope you have considered the fact when i have tried installing windows multiple time through bootcamp it gives me an error no bootable usb detected. Enter a bootable device and press any key.

Also, If i get the error once again this time do you want me to install windows from EFI BOOT

No worries. 2011 Macs do not directly support W10 as shown in Use Windows 10 on your Mac with Boot Camp - Apple Support .

However, you can install W7 using a DVD, and then an in-place upgrade to W10 will work. W7 on 2011 can be installed in legacy BIOS/MBR mode.

Thanks a lot. I have already installed windows 8 for now. will try to update it to windows 10 tonight. I am sure i have to buy it now. I am also worried if it will support the sound driver for me as it did not when i EFI booted my system.

Also, is there still any way through which i can get windows 10 for free.

If W8.1 is correctly installed (using BIOS/MBR) and your sound works properly, It should continue to work, if you upgrade without any issues. EFI Boot is not supported on your specific model.

No.

Hi Loner T,

Thanks for your help.

This is how i installed windows 10 perfectly on Macbook Pro late 2011.

Used Bootcamp to create USB for windows driver
Installed Windows 8 via Bootcamp by using Windows Disk
Installed Windows Driver from USB created by Bootcamp. Check if all the drivers were installed perfectly
Updated windows 8 to Windows 10 from Microsoft Website
All the drivers were updated automatically and working fine.

Just do this anyone who wants to have windows 10 you wont face any problem this is the best way to do it. I have tried all other way but none were quite useful.

Excellent. Please remember to set up good and regular back ups for OS X and Windows. Also, create a Windows System Restore point.

Dear Loner T

My Mac is MBP mid 2012 running Sierra. I've installed clean bootcamp windows 10 on a second SSD. Ofcourse it has to boot in UEFI mode and cause my sound card not recognized. My question is is there anyway to convert my bootcamp from GPT/UEFI to MBR/Bios without reinstalling?

I appreciate any help in advance.

No. However, you can use products like Winclone to backup Windows and restore them as legacy Boot (MBR/BIOS).

Dear LonerT

Thank you for your feedback. However I've asked guy from Winclone Support. He said running bootcamp on a second hard drive (likes using HDD Caddy on Optical Bay) absolutely required EFI boot, not legacy boot. You cannot using Legacy boot in this scenario whatsoever. Have you given a test on your solution restore bootcamp as legacy Boot. If you've succeed, I would give try.

Btw, could you teach me the way to perform clean install bootcamp window 10 in legacy boot on second HDD (not upgrade from older windows version)?

I appreciate your time.

Peace.

On a secondary HDD on a 2012 Mac, BIOS/MBR does not work, as corroborated by the Winclone folks. Even EFI has issues on older Macs, with IO issues.

If you do need two drives, I recommend putting Windows in the Main bay drive, and OS X in the Optibay. I install Windows with the Optibay SATA connector disconnected and use a USB Installer on a 2012 MBP. Once installed, I will reconnect the Optibay SATA connector.

On a Mini, I use a Fusion drive, but install Windows on the SSD part (128GB for OS X, 128GB for Windows on a 256GB SSD). I manually partition the Fusion drive using diskutil cs commands.
