Hi there,
I was trying to install windows 7 on my 15" late 2011 MBpro. I am using a usb stick with an .ISO file. Everything is going well until te mac restarts to boot from USB, but there can't be a bootable usb found. I tried EVERYTHING but nothing is working. Tried different USB's and nothing works. I spend more than 2 days on this but noting works. Anyone who can help me?
MacBook Pro, OS X El Capitan (10.11.1), null
What is wrong with your built-in Optical drive?
Sorry what do you mean?
If it is a 2011 Macbook Pro, it should have a built-in CD/DVD drive.
Ahh, i know but i don't have a cd/dvd i have just a .ISO file from windows, so i managed to created te usb option.
Your Mac will not install Windows from a USB. Burn the .ISO to a physical DVD and install Windows using BC Assistant.
You can use a USB stick (provided that it has enough space), but you MUST use Apple's BOOTCAMP assistant.
And is just burning the .ISO file enough or do i need to do something with it?
But, i use bootcamp and the USB is setup correctly but once my mac tries to boot up the windows install from the USB it says "no bootable device found"
All you need is a usb stick and the plain iso file somewhere (desktop). Bootcamp Assistant will ask you to select the file and usb, do partitioning stuff, etc.
Burn the ISO to the DVD, run BCA and insert the DVD, and follow BCA prompts.
Did that, but got stuck at the windows installation
But, i managed to install windows from a usb on my iMac, but the exact same thing don't works at my mbpro.

Not all Macs support USB booting. Read the Bootcamp info.plist, if you are interested. Modifying this file leads to black screens and error messages as OP has seen.

What year/model is your iMac? If it does not have a built-in Optical drive or a 2012 or later model, it will support USB installation. Please also see previous post.
If BCA provides the option to create a USB Installer, then you can use it. If you modify Info.plist, it will not work on 2011 models.
Late 2011 15" i indeed modify the .plist file in order to get the "create usb " button in BCA, this trick worked on my iMac but not on my mbpro, i mean i can see the button and i can use it, but when the usb is ready and the mac restarts to boot from usb it says "no bootable device found"
