Realistically this problem is most often caused by the boot manager being corrupted or changed. To fix this in Windows 8 open the charms bar and click settings. Now click modify computer settings on the bottom of the menu that opened. Click on the General tab and scroll all the way to the bottom of the list to the right. Under advanced startup click "Restart Now".
The computer will load into the Advanced Startup screen. It should be a blue screen with white writing. Click on troubleshooting.
If you have data that you don't want to lose you should click on Refresh your PC. It will do just that and leave your files alone. It is however not as effective of a trick and the second option. If this doesn't work backup your data and try the Reset instead.
If you don't have files to lose or don't care if you lose them click on Reset. It will take a bit of time but will reinstall Windows and rewrite your boot file.
Hope this helps!

Thank you, ScottyC.
I followed your instructions to "Refresh your PC" and the "Operating system not found" message is no longer appearing. Although Refresh your PC does keep most of your files intact, be advised that it will remove some of your applications. Below is the list of applications that were removed from my PC that I had to reinstall:
Adobe Flash Player, Blackberry Desktop Software, Brother and Cannon Print drivers, CampanionLink, Microsoft SkyDrive, Microsoft Office 13, Firefox & Quicktime.
So, although I had to spend about 90 minutes reloading all of these applications, I am grateful that this message is no longer appearing. However, since the workaround seems to be just entering Ctrl-Alt-Del after the "Operating system not found" message appears, I might recommend doing that until you have the time to reload your applications.

when operating system not found appears hit ``clear alt delete`` and the system load normally, i'm not an expert but it work.

When the operating system is not found and you hit ctrl alt delete, you're telling the system to restart. That's it. It doesn't reload defaults, it doesn't correct any startup errors. It's the same as hitting the power button. You're better off just taking care of the issue before it becomes more serious.

I am experiencing the identical issue and my laptop is only 3 months old. For the last 2 wks I have received the message "Operating system not found" the first time I boot up the laptop or wake it from sleep. The 2nd time there is no issue. I am also quite concerned.
