I used this method on my late 2011 mbp and I now have windows 8.1 pro running on it perfectly::īefore you do anything, make a backup of ist or the whole Boot Camp Assitant app so that you can go back if necessary. It'll allow you to create a bootable USB on older macs through boot camp without an optical disk. If someone managed to install Windows 7 on his/her iMac with Yosemite using a USB Key, please help me understand why I can't see the USB as a boot option.įound this on an apple forum.
I read some stuff about reFit ( ) and GParted, but I just don't know how to use them. Result: I never managed to have my Unetbootin-formatted USB key appear on this screen :( So I tried to use Unetbootin ( ) to make my USB Key bootable, and tried to boot on it through the screen that appears when you maintain the Option key (Alt button) while starting the mac. So I follow the process religiously and end up with the classic and famous boring screen 'No bootable device - insert boot disk and press any key'. However, its optical drive does not work, so I chose the USB key solution using the trick of modifying the file ist of Bootcamp (type 'usb bootcamp youtube' in google to see a video of this trick). I am trying to install Windows 7 on it via Bootcamp. I have an iMac (bought in 2011) and I recently upgraded it with Yosemite.
