    I'm trying to install Windows 7 sp1 64bit on a mid 2009 intel core 2 duo MBP. When i hold down alt I'm presented with OSX HD, Recovery, A DVD Symbol for Windows and a DVD symbol for efi, no bootcamp HD. Has some gone terribly wrong here or do i just simply boot from efi? I tried booting from windows but nothing happened. This is completely different process from how Win7 installed on my MBPR which if I remember correctly restarted it self and went straight into the installation process of Win7.

    One more thing, the DVD drive on this mac is broken, so I'm installing via a external USB DVD drive, I also tried installing via a bootable usb but the mac did not want to recognise it.

    Many Thanks,

    first step

    create in OS X a bootcamp partition,
    download Bootcamp drivers to an USB stick,
    after that, you can boot usually into your Win 7 DVD holding Alt,
    but, it is known, that an Mac with a build-in DVD drive doesn't boot
    to an USB stick with bootable Windows!

    either way, you have to ask yourself, if you want to install via Efi or Bios mode,
    may be you can only install via Bios mode with your Mac.

    Thanks a lot, but the answer i'm looking for is weather i select the dvd symbol saying 'win7' or 'efi'.

    Win7 vs Efi

    if you choose Win7, your istallation will be in Bios mode,
    usually with fewer, if any driver problems, but with a slower
    boot time. Installation in Efi mode results in an overall faster
    Windows, due to AHCI, faster boot time, but maybe you don't have
    sound and sleep mode.
