1. EFI Boot= Grub menu, loads from stick for ~45 seconds then reboots machine.
When inserting noefi as kernel parameter, there is no change in behavior. FYI I'm inserting it right after 'rd.dm=0'.

2. *EFI Boot= Grub prompt, no menu
grub> root
  (hd0,2,a): Filesystem type unknown, partition type 0x0
grub> findiso
grub> root
 (hd0): Filesystem type is iso9660,  using whole disk

1. EFI Boot= Grub menu, loads from stick for ~6 seconds, then beeping, must force shutdown.
With noefi as kernel parameter, no change in behavior.
