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?

How can i reinstall the ntoskrnl.exe when it is corrupt


Assuming a couple of things:
1. Your OS is Windows XP
2. This is the error message you are getting -
"Windows NT could not start because the following file is missing or corrupt:
Winnt_root\System32\Ntoskrnl.exe
Please re-install a copy of the above file."

To reinstall notskrnl.exe, do this:
  • Start the computer by using your Windows XP CD-ROM. Press any key to boot from the CD.
  • After the setup files are finished loading press R to repair using Recovery Console.
  • When you are in the recovery console, select the installation to log on to (usually number 1), and then press ENTER.
  • Login to the Administrator account by typing the password for this account, and then press ENTER.
  • At the recovery console command prompt, type the following command, and then press ENTER:

    For Uni-Processor systems: expand <cd-drive>:\i386\ntoskrnl.ex_ <hd-drive>:\Windows\system32\ntoskrnl.exe
    For Multi-Processor systems:expand <cd-drive>:\i386\ntkrnlmp.ex_ <hd-drive>:\Windows\system32\ntoskrnl.exe
    Note In these two commands, the <cd-drive> placeholder represents the drive letter of your CD drive, and the <hd-drive> placeholder represents the drive letter of the hard disk on which windows is installed.
  • If you receive a prompt to overwrite the file, press Y.
  • Type exit, and press ENTER at the command prompt.
  • You should now be able to boot up properly.

    Tip

    If your laptop is running slow and applications are taking a long time to load...


    If your laptop is running slow and applications are taking a long time to load here are some tips that may help you solve your problem. Laptop computers are not much different than desktop PCs. They both require maintenance to keep them preforming the way they should.

    First of all of if this is a recent problem that started after you’ve installed or uninstalled a program. Use your restore feature and go back to a previous state when you know your computer ran good. You will also want to update your antivirus software and run a full scan, the same with your spyware software.
    Be sure to update the definitions on each program before you run your scans. You want to make sure your computer is free from any viruses or spyware as these will really slow your laptop down.


    Unless you have a hardware problem like not enough memory or your hard drive is going bad.The biggest reason for laptops running slow is because of a corrupt registry. Especially if you are running Windows Vista. You may have found a lot of incompatible programs or software, and had to uninstall them. They leave behind invalid registry keys and orphaned entries.
    You need to clean these out.
    Your Windows registry is like a large database, all your software has to reference it when it loads to check for the correct settings. The same as when your computer starts up or shuts down. Your registry is a heart of your system. Any corrupt or damaged, registry entries will really slow down your operations.


    Cleaning and maintaining your Windows registry is very important. It’s sort of like giving your computer a tuneup. Windows does not have a tool built in for you to do this with. So you’ll need to download a third-party software program for registry repair and cleaning.


    You can edit and repair your registry manually, but it’s not recommended. Even experienced computer technicians have a hard time doing this. They all use software. Besides a few delete or alter the wrong file your computer may become unusable. Software that is made for registry repair is much safer and efficient. With a click of your mouse you can scan your entire computer in a couple of minutes. You can also make a backup and restore point before you make any changes just to be safe.


    Depending on how much you use your laptop. You should preform weekly registry maintenance, of course, this applies to any other computer you own to. If you follow the tips above your laptop should not be running slow anymore.
    The only other thing I can think of is if you upgraded your operating system to a newer version of Windows like Vista you may not have enough memory now. Memory upgrades have really come down in price lately, and are fairly easy to replace in a laptop.

    It keeps saying that ntoskrn1.exe is missing


    It is pretty much crashed....hard. Might want to reload the OS. Yes you can recover from that, but it is not worth the time and frustration to do it...Provided you can afford to lose whatever you had on the primary partition (C:\) drive. Let me know if you need other asst. It is a little complicated to explain. How many machines is this affecting? All of your E-Machines?

    Do you have a Windows CD that came with your computer? If so do you know how to boot from it by inserting it into the drive and then pressing F12 just after you switch on your PC? If you can do this then you could try the "repair" option from Windows Setup, this might fix your missing PC problem.
