Windows 7: Serious error 0xc000009a

09 Oct 2013   #1

Windows 7 professional 32 bit
Serious error 0xc000009a

My laptop with Windows 7 professional 32 bit has started to show an error every time I try to start op from Hibernation. It comes up with the following message:

The computer could not return from hibernation
Status: 0xc000009a
Information: A serious error occurred during the process of recreating data.
File: \hiberfil.sys

I do not have a installation disc since it was a pc I was given by my boss because the company got new laptops.

What to do?

Can I for instance re-install Windows 7 without a disc?

It seems to work! Nice.

What's the magic and how come it suddenly started to make trouble?
