Q: Boot camp drivers install not fully

At first I have problems with igdkmd64.sys, then I reboot against to win and reinstall boot camp drivers. Probably all drivers was installed except audio drivers. I have no audio output in settings.

I try to install only audio drivers, but they are wasn't installed.

This problem can happened because I had problem with GPT and I create partition not by boot camp? I create it in disk utility than delete in win installation and create new.

A 2011 Mac does not support EFI Boot properly. Creating a partition using DU does not create an MBR (unless it is formatted as FAT), which will install using EFI boot by default. This will cause the EFI layer to hide Audio devices.

Yes, BC Assistant will do it properly but it will not support W10. If you want to install W10 directly without an upgrade from W7/W8.x, please ensure you create a FAT partition using DU and verify the MBR (output of sudo fdisk /dev/disk0) and then boot from the W10 DVD installer (you cannot use a USB installer on 2011 due to the EFI vs BIOS mode issue).

You will have the same issue with W8+ that you have with W10. A USB/EFI Installation is not supported on a 2011 Mac, which has a built-in Optical drive.
