That's what I use and what can be found on varoius forums and wikis. It works neither with rEFIt nor grub for me. Perhaps I am not using the = character, I should check that but bless does not report any error and it actually changes the information (there is another bless option to show the state). > > bless writes the location of boot file to the hfsplus header. bless > doesn't work on FAT. > > At startup, you need to press the Option key to show startup disk, and > select the usb disk.

Can't the installation pre-create an efi image that contains most options? AFAIK the size of the image is not of much concern on efi so creating a mostly complete image would simplify things.
