Ok, I have to respond to this because something glaringly obvious had been completely overlooked.

People come to this article because they are seeing this error code and their system won't start. Your solution is to do things that can only be done on a system that's started.

How the heck does that make sense?!?!

If these solutions can/should be done in safe mode, that would be step number one but you don't mention that.

Clarification needed please.
