I want to create a bootable USB installer on Mac OS X and use the USB to install it on my new Dell Precision 5520. I am using Mac OS X because it’s the only computer I have beside the formatted Dell.
I followed the instructions on: https://www.pyrosoft.co.uk/blog/2013/01/09/creating-a-bootable-usb-stick-from-osx/ to create the USB, but when I run it on the Dell I get the following error:
ERROR Failed to mount /dev/loop
Any help appreciated. Thanks
