lornaevo Posted August 10, 2013 Share Posted August 10, 2013 So i created a bootable mountain lion usb, but when I try to boot from it, my Dell dimension E520 flashes a quick boot0 message amd then loads into windows. Can anyone help with this? Link to comment https://www.insanelymac.com/forum/topic/291139-dimension-e520-wont-boot-from-usb/ Share on other sites More sharing options...
