I take it you did the System Recovery from Safe Mode, can't you just go down and shut down then when you start up again hopefully it will start up normal, never had to do it so don't know if this will work but I can't see it will hurt to try.
He might have gone to BIOS where exit is not too obvious. The easiest way is shut down by pressing Power Button, then restart and boot normally..not safe mode or any other mode..... just normal boot.
Are you watching it boot, or walking away? It could be that your system is telling you you had problems and picking the Recovery as an option, giving you like a couple of seconds (up to 30) to change back to a normal boot sequence....

If you had just attempted to do system recovery, you might be trying to get out before it is completed. (some techie call it FBI GUI manager). Let it complete. Try to just leave it alone until it is done. Sometimes SR takes longer than "normal"...like "forever"
