No, I don't mean that.

I mean we don't know what the problem was. We have almost no info.

So what you should have done, it seems to me, was try to find out what
the problem was, and then, depending on what you found, try to fix the
problem.

Instead, it seems to me that you went from the first step to the last
-- "OK, I'll boot from USB" to "fine, all over, let's reinstall my
bootloader!"

You bypassed all the steps in between:
* what happened
* what did it do
* can I fix it?
* can I prevent it happening again?
* OK, I have identified the underlying problem
* I have fixed it
* I have fixed my disk

I know. That is what I am saying. You totally bypassed all the most
important steps in the process.

So, yes, it might happen again. It might not. We don't know. You don't know.

It's like the joke about troubleshooting:

«
A software engineer, a hardware engineer and a department manager were
on their way to a meeting in Switzerland. They were driving down a
steep mountain road when suddenly the brakes on their car failed. The
car careened almost out of control down the road, bouncing off the
crash barriers, until it miraculously ground to a halt scraping along
the mountainside.

The car's occupants, shaken but unhurt, now had a problem: they were
stuck halfway down a mountain in a car with no brakes. What were they
to do?

"I know," said the department manager, "Let's have a meeting, propose
a Vision, formulate a Mission Statement, define some Goals and by a
process of Continuous Improvement find a solution to the Critical
Problems, and we can be on our way."

"No, no," said the hardware engineer, "That will take far too long,
and besides, that method has never worked before. I've got my Swiss
Army knife with me, and in no time at all I can strip down the car's
braking system, isolate the fault, fix it and we can be on our way."

"Well," said the software engineer, "Before we do anything, I think we
should push the car back up the road and see if it happens again."

You didn't even bother going back up the hill. You just got back in
and drove off. That's what I was shocked about.
