How Do You Create A Bootable Usb For A Mac Using Avast
My MBA 2012 with OS X 10.9.4 Mavericks won't boot anymore - it simply freezes after the initial jingle. I already tried resetting NVRAM and SMC, but to no avail.
I don't have any time machine backups. However, I still have a disc image of Mavericks sitting on an external hard drive, a USB stick and access to a notebook with Windows 7.
I haven't yet found any tutorial on how to create a bootable USB drive on Windows in order to reinstall OS X on my beloved Macbook Air. Any help would be greatly appreciated!
