He'll just tell you to reboot.
Apologize for the tangent, but a true story about booting from my career 30 years ago.
Our base had just put in a new Unix network and after a few months of running fine one of the servers would hang when you started it. We were troubleshooting it and couldn't get it past that hang point, so we decided to call the help desk.
I told the other Sgt that we might as well go ahead an reboot it now because that is the first thing they are going to ask you to do. So, we reboot, it hangs up again and we call the help desk. They say, "reboot it". We say, "we just did". They say, "reboot it anyway".
Me having a bad day, got a bit testy and used my combat boot to lay a good kick on the front of the $20,000 server. Magically, after the kick the server goes past the point where it was hung and comes up fine. I say, "tell the guy booting it worked and hang up".
It turns out the server had an intrusion detection system we didn't know about and someone had not closed the front cover completely, so it would just stop. My kick closed the door completely. Most satisfying help desk call of my career..............
