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).
