You can't use "grub2-install /dev/USBDRIVE", that's for non-EFI systems.
And as Chris explained, you can't use "grub2-install" either or it
will mess things up badly. If you have the usb drive EFI partition
mounted at /boot/efi, then re-installing "grub2-efi" should fix the grub
install on your usb drive.
As for why the live image isn't booting, that really seems like a BIOS
problem.
