</I>FYI:
Fedora 17 Beta uses GPT. and sucessfully boots Live USB's in recent
tests I have done.
1-)Full install of a live .iso to a 8 GB USB; use fedora disk utility
to format: Custom install: GPT(boot) 2; /boot 500; / balance of the USB
no swap.
2-) dd write (to 2 GB USB) also works for the live .iso's
dd if=Fedora-17-Beta-x86_64-Live-Desktop.iso of=/dev/sdb bs=2M
3-)EFI USB's that boot on a MacBookPro i7
./tools_livecd-iso-to-disk.sh --format --efi --overlay-size-mb 300
--home-size-mb 175 --delete-home --unencrypted-home
Fedora-17-Beta-x86_64-Live-Desktop.iso /dev/sdb1
