2.4 UNetbootin (Other Linux, Windows, Mac).

It didn't work perfectly for me - but the issues I ran into were solved fairly easy with Google searches. Macbook Pro, Retina, 13', Early 2015 (120GB SSD, 8GB RAM) As always, backup your data beforehand just in case! I didn't have access to one so I just installed a VMware trial version on my Mac and used it for the Windows part of the setup. You'll need a computer running Windows to do this entire process. The issue you are running into is that you need to setup an EFI boot in order to be able to boot and run Windows off a USB drive. I ran into this issue a while back when I wanted to run Windows off and EHD so it wouldn't take up any space on my Macbook's HD. So, I seem to be effecting something with that command, but I still can't boot from my Windows bootable USB drive. The log in screen, though, was much slower than usual, as if something else was happening in the background. Boot was slower, but then I was presented with the normal log-in screen. Sudo bless -mount '/Volumes/WDO_Media32/' -legacy -setBoot -nextonlyĪnd then did a restart.

Or maybe a better question, if there isn't a simple answer, would be what does Bootcamp do to allow booting from a Windows install DVD or to allow Windows, once installed, to boot?ĮDIT: I was able to sort of get results using the bless command in Terminal.

So, what do I have to do to get my Mac to recognize and boot from another OS on a USB flash drive? I have had the same issue trying to use the Ultimate Boot CD on a USB, various Live USBs for Linux, etc. Specifically, I was running Windows 7 on my Mac to create the bootable disk, which has Windows Defender Offline on it. I know the drive works and is bootable, because it works with my friend's Windows PC. I'm trying to get my Mac to boot from a USB flash drive.
