Q: bootcamp driver issues

okay so i installed windows to go onto an external hard drive and i can boot into it just fine with holding down the options key and selecting efi boot. Everything works fine but i have 3 problems after installing bootcamp drivers(the latest 5.1.5621) :

1) the sound doesn't work

2)Cant adjust the brightness and in setting it says disabled

3)whenever i install the intel graphics and its about to complete a blue sad face appears and says system_thread_exception_not_handled(igdkmd64.sys) but when i                               remove the intel folder from drivers in bootcamp, the setup runs fine bt still no brightness nor sound

 

Can someone please help me solve this ?

 

Thanks

MacBook Pro, OS X Yosemite (10.10.1)

    The Apple Bootmanager looks for EFI boot, which is its native default. Booting from USB still does not address the NVRAM setting.

    No. CSM-BIOS is a compatibility layer and has no user interface.

     

    The only method to invoke the CSM-BIOS layer during a boot is using the bless command. Please see https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/ man8/bless.8.html.

    See the description of the two qualifiers --legacy and --legacydrivehint (which are used by Bootcamp).


    My suggestion is use the tools you already have, namely, Bootcamp Assistant, and let it partition and install Windows. Reverse engineering Bootcamp is quite a bit of work.

As I understand it , the audio drive does not work for that was installed using the UEFI mode, but I can not get him to install the windows without being in UEFI mode . someone could help me ? I wanted to turn the windows into my MBP necessity reasons. hesitate a secret q I can the boot without using the UEFI mode? Thank you ! Another detail , not in UEFI mode can not install windows 7.

    PT_BR:

    Boa noite, tentei todos os procedimentos que aqui foram falados, porém meu MBP 13 inicio 2011 so instala windows 8 ou 8.1 em modo UEFI, pelo Bootcamp ele reinicia e fica tela preta e o MBP é como se estivesse desligado, porem no meu ver ele esta travado, ja esperei mais de horas e nao sai da tela preta. criei o USB com os drivers, deixei plugado no MBP enquanto ele reiniciava, fiz o teste sem o USB e em todos os teste sempre trava na tela preta. Pelo que entendi, o drive de audio nao funciona por que foi instalado usando o modo UEFI, mas nao consigo fazer com que ele instale o windows sem ser no modo UEFI. alguem poderia me ajudar ? queria muito rodar o windows dentro do meu MBP por motivos de necessidade. exite algum segredo q eu possa da boot sem usar o modo UEFI? Obrigado! Outro detalhe, nem em modo UEFI consigo instalar o windows 7. Desculpe a traduçao, sou brasileiro e usei o google tradutor para me ajudar :).
