Question

The operating system couldn't be loaded

My HP elitebook 8470p 64 bit Ram 8gb hdd 1 tb running windows 8.1 pro has been having freezing problems and programs not responding and sometimes closing in the middle of an operation. I think it has been infected by a virus although I have installed various antimalware softwares eg Malwarebytes, Super anti-malware, Emsisoft antimalware, Eset nod32 antivirus, Kasperky removal tool, Hitman pro among others but none of them seems to detect the problem. I used adwcleaner one time and after it had finished scanning it asked for a reboot to complete the cleanup process. I rebooted but after login a black screen appeared . I tried to press Ctrl+alt+del which opened up sometimes but when I pressed task manager the black screen with a movable cursor shows up again. I also tried to boot into safe mode by pressing shift+ restart on the login screen which worked very few times because often times it would just restart back to the login screen. Anyway while in safe mode I tried different solutions I googled such as SFC/scannow command, deleting the Windows activation folder, uninstalling the graphic card drivers, deleting the file: Windows.UI.Immersive.dll etc but none of the solutions worked.

After a while I came across this solution bootrec \fixmbr which I used and after reboot I pressed ctrl+alt+del and when I tried to open task manager the system opened up although it took around 5 minutes to load all the programs. I used it for a few hours although it would occasionally freeze and at one point it froze for about 10 minutes so I shut it down and when I started it the black screen error came back.

After multiple struggles to enter safe mode I tried another solution that was about deleting all the antivirus programs. Before this process could be completed my pc suddenly shutdown because I had not plugged in and battery had reached zero without my knowledge since while in safe mode there is no notification about the battery life. Anyway when I tried to boot my laptop it immediately went to Automatic repair but after scanning it said that automatic repair could not repair your PC so I pressed the advanced options.

I tried startup repair which failed.

I tried Refresh your pc which said There was a problem refreshing your pc. No changes were made.

I also tried System restore which gave me this error: ( System Restore did not complete successfully, Your computer's system files and settings were not changed.

Details:
System Restore failed to extract the original copy of the directory from the restore point.
Source: %SystemRoot%\registration

Destination: ComPlusStaging

The restore point was damaged or was deleted during the restore.

You can try System Restore again and choose a different restore point,If you continue to see this error, you can try an advanced recovery method.)

I tried to get into safe mode through the startup settings but when I press f4 the automatic repair loop keeps on starting.

I decided to disable the automatic repair loop to see whether I would solve the problem which I did by using this command ( bcdedit /set {default} recoveryenabled No )

This brought me to a blue screen with this error:

(The operating system couldn't be loaded because a critical system driver is missing or contain errors.

File:\WINDOWS\system32\DRIVERS\klelam.sys
Error code:0xc000000f

Choose one of the options below to address this problem.

Press ESC for recovery
Press Enter to try again
Press F8 for Startup Settings)

I have also inserted a windows 8.1 recovery disk and tried to install windows but after following all the instructions the final response is: ( The computer started using the Windows installation media. Remove the installation media and restart your computer so that Windows starts normally. Then, insert the installation media and restart the upgrade. [Do not select Custom advanced to perform an upgrade. Custom advanced installs a new copy of Windows and deletes your programs and settings.]


Please assist because I don't want to lose my personal files but I have no problem if all the programs were removed.

You'll only lose what you didn't backup. So I would start with that.
Boot from a Linux disc or stick (both are free to make) and use its file manager to copy everything you want to save either to the cloud or to an external hard disk.

Once your data is safe, try to recover again.

Clarification required

In reply to: Re: lose personal files

Thank you so much for responding. I am going to try this at least to back up my files. I however don't understand what you mean by try to recover again since I've tried refreshing,restoring and even reinstalling windows with no success. Please clarify. Thank you.

Recovery disc

In reply to: The operating system couldn't be loaded

Where did that come from?
Is it something that came with the machine or you made with the machine?

If you can get 'your stuff' off the hdd with linux, then use the factory restore media to reload the OS.

If you can't get 'your stuff' off the hdd, remove the hdd and install a new one.
Now use the factory restore media on the new hdd.
