I have just had a really bad thunder storm… Foxtel was cut off for a few seconds, and there were a few short power outages. One of which dropped out my Linux server from power and caused it to reset. This could have been fine except for one thing… The computer did not restart.

When I put the new HDD drive in a few days back it had the wrong order for the booting from drives. It was set to boot from the secondary drive and if that did not work try the primary drive. And this was fine until I formatted the secondary secondary drive. Then the next time the computer tried to restart (which was tonight) it refused to since the computer could not find the operating system.

Changing some BIOS settings fixed this. And the computer has now been restarted. Things are working again!
