USB Key Labelled EFI Boot

If you have created a Mac OS X bootable USB Key and it shows up as EFI Boot when you are at the boot selection menu then you can rectify this via the following Terminal command

sudo bless --folder /Volumes/VOLUMENAME/System/Library/CoreServices --bootefi

replace VOLUMENAME with the name of your USB Volume, so I named my 10.8 Key ‘Mountain’, so my command would be

sudo bless --folder /Volumes/Mountain/System/Library/CoreServices --bootefi

then enter your admin password and reboot

Hold down ALT to get back to the boot selection menu and you should now have the VOLUMENAME displayed under the USB Device, rather than EFI Boot
