I'm trying to get my Mac to boot from a USB flash drive. I know the drive works and is bootable, because it works with my friend's Windows PC.
Specifically, I was running Windows 7 on my Mac to create the bootable disk, which has Windows Defender Offline on it. I have had the same issue trying to use the Ultimate Boot CD on a USB, various Live USBs for Linux, etc.
So, what do I have to do to get my Mac to recognize and boot from another OS on a USB flash drive?
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?
EDIT: I was able to sort of get results using the
blesscommand in Terminal. Specifically, I used
sudo bless -mount "/Volumes/WDO_Media32/" -legacy -setBoot -nextonly
and then did a restart. Boot was slower, but then I was presented with the normal log-in screen. The log in screen, though, was much slower than usual, as if something else was happening in the background. So, I seem to be effecting something with that command, but I still can't boot from my Windows bootable USB drive.
