Came in this morning to reboot a NAS and server.
NAS won't log in. Ok, sod you. Pushed power button to switch it off. Waited obligatory 20 seconds for HDD's to spin down.
Jabbed power button. Boots.
Disk boot failure.
>Panic mode ENGAGED<
Check all USB ports, nope, no USB sticks or HDD's.
Check BIOS, all is good and correct.
Reboots.
Disk boot error. %@@@$
Pulled power, waited for 5 minutes, plugged power back in...
...and it boots beautifully.

Nothing like having a critical server/service boots up without issues.
