    How to install windows on iMac using a USB flash drive?
    I had tried to install windows 7 on my imac running os lion through a bootable usb as it's superdrive is broken.
    Firstly I created the bootable usb of windows 7 from my friend's laptop using the instructions on this website

    How to Create a Windows 7 Installation USB Drive | Windows.AppStorm ion-usb-drive/

    but bootcamp would raise an error saying disk could not be found. So I modified the info.plist file from bootcamp package contents and created an iso of the bootable usb drive. Bootcamp then allowed to create a windows install usb through the iso and partitioned the hard disk too but after doing so the computer restarted with a black screen and a message ' insert boot disk and press any key'. Now I've deleted the windows partition and really need help installing windows 7.

    Specs:
    27" iMac i7 (2011) 10.11, Mac Mini i5 (2014), iPhone6s, Apple Watch, iPad Air 2, New AppleTV (4?)
    Only the version of bootcamp on Macs that came without optical drives supports installing Windows from a USB drive I'm afraid.

    However, there is a way to do it with reFit.

    You can skip the first bit if you already have a bootable USB with Windows 7 on
    Not been around these parts for a while. Trying to change that . .

    Specs:
    Imac 27" Retina 3.3GHz, 512GB Flash, 16GB memory, OS X.11.4.
    And be aware Windows 7 will require activation and will not activate if it is installed on your friend's laptop. Have seen the copy activate asnd the original install become marked as none genuine.
    Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!

    I followed all the instructions from this blog

    Installing Windows on a Macbook Pro without a Superdrive | Bagel Belly Blog

    Everything worked well upto the point when I had to shut down vmware and reboot using refit which I did successfully too...but then windows opened and the last part of the setup was completing, then it restarted again. Again the refit showed up, I selected windows, the logo came and then the screen went blank....I waited for quite sometime hoping something would show up but unfortunately nothing happened...the screen was stuck on the black screen ...since I was so close to installing it, I just hope there's a solution for this problem...plz help me..

    Your best course is probably replacing the optical drive and buying your own Windows 7 CD.
