OSX El Capitan - cannot make bootable usb stick with boot camp I meticulously followed this tutorial, and this worked for me in 2014. I have a 4GB usb stick plugged into the computer. It should be enough for windows 7, a partition which no longer boots and I am hoping to run startup repair on it from the install USB so I don't have to start over clean.

This is the screen I get after following this tutorial where the Info.plist file of bootcamp is modified to let the USB creation happen (same screen as before):



Has anyone encountered this issue?
If you find no option to select your external USB drive as an ISO target - are instead directed to install on your repartitioned hard drive immediately - open the info.plist and add your model identifier to the following:

&lt;key&gt;ExternalInstallOnlyModels&lt;/key&gt;
&lt;array&gt;
    &lt;string&gt;MacBook8,1&lt;/string&gt;
    &lt;string&gt;MacBook9,1&lt;/string&gt;
    &lt;string&gt;MacBookAir7,1&lt;/string&gt;
    &lt;string&gt;MacBookPro11,5&lt;/string&gt;
&lt;/array&gt;
