Question about Sony VAIO VGN-CR220E/P Notebook

No restore cd, windows won't load, corrupted ntoskrnl error msg

After the last Vista update on the laptop, it slowed down to a crawl even though it has 2gb RAM and only 50gb of 200gb used on Hard drive. I tried a few combinations of recommendations from the web as well as spotmau 2008 to speed it up. Obviously I messed up something because all it does now is give a error message when windows try to boot which says corrupted ntoskrnl file. I did not create a restore point nor a back up cd from the HD. The laptop does not come with any Vista cds either. The restore CD downloaded from microsoft does not help. I've viewed the partitions on the HD and they seem to be fine. Is there a way to restore the corrupted file or the entire operating system.

    To clarify. I have no Vista cd because none came with the laptop. I now know that I was supposed to create a restore cd when I purchased it before something like this happened but I didn't. Is there a way to restore or repair the corrupted file in windows from the partition at this point. My problem is that I have no vista cd to reinstall the OS.

You might try tapping F10 after you see the Sony screen, and see if you computer will go into the recovery mode from the hidden partition. I just did that to my Sony, and it worked great.

Let me know, OK?

Keyboard issue

This issue has also been known to be caused by a short in the ground wire in the keyboard cable. Make sure this is not the cause of your error by replacing the keyboard with a different keyboard or just disconnecting the keyboard from the computer.

Miscellaneous corruption

Before trying any of the below recommendations it's recommend that you load the last known good configuration.

Corrupt boot.ini file

This issue is often caused when the boot.ini is missing or improperly configured. This issue often arises after a user has recently added or removed an operating system on the computer or added or removed hard disk drives in the computer.

Make sure the line pointing to the operating system and its drive and partition is properly configured in the [boot loader] and [operating systems] section.

Missing boot.ini file

Microsoft Windows XP users:

If the boot.ini is severely corrupted or missing a user running Microsoft Windows XP can rebuild the boot.ini to resolve this issue.

Microsoft Windows NT and Windows 2000 users:

To restore the original boot.ini file in Microsoft Windows NT or Windows 2000 you will need an ERD and follow the below steps. If you do not have an ERD you will be unable to follow these steps.

  1. Boot the computer with your Windows NT three setup diskettes or the Windows 2000 setup disc.
  2. In the setup menu, type R to start the repair.
  3. When prompted for the ERD diskette insert the diskette and inspect the startup environment.

Missing or corrupt ntoskrnl.exe file

If the ntoskrnl.exe file is corrupt or missing this can also generate the error. To restore this file follow the below steps.

  1. Insert the Microsoft Windows XP CD. Note: If you have a recovery CD or a restore CD and not a Microsoft Windows XP CD it is likely the below steps will not resolve your issue.
  2. Reboot the computer, as the computer is starting you should see a message to press any key to boot from the CD. When you see this message press any key.
  3. In the Microsoft Windows XP setup menu press the R key to enter the recovery console.
  4. Select the operating system you wish to fix, and then enter the administrator password.
  5. Type expand d:\i386\ntoskrnl.ex_ c:\windows\system32
  6. You will then be prompted if you wish to overwrite the file type Y and press enter to overwrite the file.
  7. Type exit to reboot the computer.

Windows NT installed on a partition bigger then 7.8GB

If you are running Microsoft windows NT 4.0 on a partition larger than 7.8GB this issue can occur if the boot files are located outside this limitation. When this error occurs your computer will have the error message as shown below.

OS Loader v4.01
Disk I/O error status=00000001
Windows NT could not start because the below file is missing or corrupt: winnt\system32\Ntoskrnl.exe
Please reinstall a copy of the above file.

If your system partition is larger than 7.8GB you will need to delete the partition and recreate the partition to 7.8GB or less. Additional information about this issue can be found on Microsoft KB Q224526.

Corrupted hard disk drive or severely corrupted Windows

Check the hard disk drive for any errors by running the chkdsk program. To do this follow the below steps.

  1. Insert the Microsoft Windows XP CD. Note: If you have a recovery CD or a restore CD and not a Microsoft Windows XP CD it is likely the below steps will not resolve your issue.
  2. Reboot the computer, as the computer is starting you should see a message to press any key to boot from the CD. When you see this message press any key.
  3. In the Microsoft Windows XP setup menu press the R key to enter the recovery console.
  4. Select the operating system you wish to fix, and then enter the administrator password.
  5. Once at the recovery console type chkdsk /r
  6. Once completed type exit and see if issue is resolved.

If after trying all of the above steps you are still encountering the same issue it's likely that Windows is severely corrupted and it is recommended you reinstall Windows.

Finally, if during the Windows installation you encounter errors it's likely that your hard disk drive is bad.

While in the middle of a system restore on my HP Pavilion dv6000 laptop with windows Vista my husband shut it down thinking it wasn't working right and now all it does is turn on and tries to boot up but...


Get the vista disc and put it in, you can perform a system restore again with the cd / dvd even thought the system restore didn't complete last time.
