• C:\CI.dll boot critical file is corrupt

  I have a Toshiba laptop with Windows 7 64-bit OS pre-installed. A backup copy of the system is stored on the hard drive. I have a 32-bit Windows 7 DVD - ROM, but if I install this I will lose all data on the hard drive, including 64-bit Windows 7 and its backup.
  Unfortunately I seem to have a virus that has corrupted the file critical boot C:\CIdll when I turn on the computer, trying to solve the problem, load files but then says he can fix it. I tried to boot into safe mode, restore to last good configuration, but nothing works: I just picked up on the Startup Repair attempt. (I am currently using a borrowed laptop) When I read the diagnosis he basically said it is unable to determine the cause of the problem, but at some point, he said that the critical boot file C:\CIdll is corrupt.
  I tried the Windows seven Forums but nothing works - I can't do a repair installation without a 64-bit installation disc and even if I was able to follow the steps described in "how to recover a loop infinitely Startup Repair loop without having to reinstall windows" it didn't work.

  The only thing I can do is go to the command prompt in the System Recovery Options. can anyoneguide me through a solution there please?

  Hi and thanks for the answers. System Restore did not work from the command prompt, but following the advice on another forum I could download a Linux operating system - Ubuntu - borrowed laptop, to help and then burn it to cd and load from the cd of my laptop. Then I could access all my Windows documents, photos and music and copy to a portable hard drive (no, I had not saved recently!). Fortunately, the laptop borrowed is also a Toshiba running 64-bit Windows 7, so Iwas able to burn DVDs of recovery from that and then restore the entire operating system from the DVD. I had also tried to burn a borrowed laptop computer rescue cd and running, but it does not pick up the virus.

  A lesson learned the hard way!

• Vista sp1 corrupts ntoskrnl.exe

  Installed Windows Vista Home Premium 32 BIT of Dell supplied DVD of resettlement on new Western Digital HDD (1 TB green SATA600 HD 64 MB) in replacement of primary transmission single partition in Dell XPS 410 with 4 GB of RAM.  Tried to update with Windows Vista Service Pac 1, downloaded from the site Microsoft Web (http://windows.microsoft.com/en-US/windows/downloads/service-packs).  Both times I tried to perform the update the following appeared on the screen: "cannot start Windows.  A recent hardware or software change might be the cause.  To solve problem 1. Insert your Windows installation disc, and then restart your computer. 2. choose your language settings, and then click Next.  3. click on repair computer.  File: ntoskrnl.exe; status 0xc0000098; Info: Windows failed to load because a required file is damaged. "Completing steps 1 to 3 following the startup repair products:"Startup Repair cannot repair this computer automatically"and the details of the repair diagnosis says"C:\ntoskrnl.exe is corrupt ".  I had to do a system restore to before I tried the update for the restart of the computer.  Any idea what the problem might be with the installation of SP1?

  .. .are say you my best plan (perhaps only) action is to reformat the hard drive and upgrade to Windows 7?

  Assuming that the computer passes Win7 Upgrade Advisor with flying colors, you can format the HARD drive and then do a clean install of Win7 (which would need to buy a commercial full version of Win7) but you can not upgrade to Win7 computer (using a version upgrade from Win7) unless Vista SP1 is installed.

  Otherwise, the best solution would be to be formatting the HARD drive and then do a clean install of Vista exactly by the (my) message of reply in this thread: http://answers.microsoft.com/thread/c44429fb-3f7c-4646-8529-5a97bb3cd0eb

  Note: The computer must NOT be connected to the internet or local networks (i.e. other computers) in its current state. All your personal data (e.g., banking online & passwords credit card) must be considered at risk, if not already compromised.

  Wish I had better news for you. Good luck!

  And that way if you have a recovery partition on your hard drive.

  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

  Data recovery:

  1. slave of your hard drive in another computer and read/save your data out there.

  2. put your Hard drive in a USB hard drive case, plug it into another computer and read/save from there.

  3 Alternatively, use Knoppix Live CD to recover data:

  http://www.Knopper.NET/Knoppix/index-en.html

  Download/save the file Knoppix Live CD ISO above.

  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

  http://isorecorder.alexfeinman.com/isorecorder.htm

  Download the Vista software from the link above.

  After installing above ISO burning software, right click on the Knoppix ISO file > copy the Image to a CD.

  Knoppix is not installed on your PC; use only the resources of your PC, RAM, graphics etc.

  Change the boot order in YOUR computer/laptop to the CD/DVD Drive 1^st in the boot order.

  Plug a Flash Drive/Memory Stick, BOOT with the Live CD, and you should be able to read the hard drive.

  When the desktop loads, you will see at least two drive hard icons on the desktop (one for your hard drive) and one for the USB key.

  Click on the icons of hard drive to open and to understand which drive is which.

  Click the icon for the USB drive and click on "Actions > Change the read/write mode" so you can write to disk (it is read-only by default for security reasons).

  Now to find the files you want to back up, just drag and drop them on the USB. When you're done, shut down the system and remove the USB key.

  See you soon

  I have Windows Vista Home Premium and has just installed SP1 upgrade.  The PC now not restart, even in safe mode.  As soon as he tries to load Vista, an error message occurs: ntoskrnl.exe missing or damaged.  I tried to boot from the resettlement drive provided by Dell, but the same error occurs.

  I ran dell seed assessment tool and the material is very good.

  What should I do to fix this file?

  Restore point:

  Try typing F8 at startup and in the list of Boot selections, select Mode safe using ARROW top to go there > and then press ENTER.

  Try a restore of the system once, to choose a Restore Point prior to your problem...

  Click Start > programs > Accessories > system tools > system restore > choose another time > next > etc.

  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

   

  If restore work not and you do not have a Vista DVD from Microsoft, do a repair disc to do a Startup Repair:

  Download the ISO on the link provided and make a record of repair time it starts.

  Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

  At the startup/power on you should see at the bottom of the screen either F2 or DELETE, go to Setup/Bios or F12 for the Boot Menu.

  When you have changed that, insert the Bootable disk you did in the drive and reboot.

  Link above shows what the process looks like and a manual, it load the repair options.

  NeoSmart containing the content of the Windows Vista DVD 'Recovery Centre', as we refer to him. It cannot be used to install or reinstall Windows Vista, and is just a Windows PE interface to recovering your PC. Technically, we could re-create this installation with downloadable media media freely from Microsoft (namely the Microsoft WAIK, several gigabyte download); but it is pretty darn decent of Microsoft to present Windows users who might not be able to create such a thing on their own.

  Read all the info on the website on how to create and use it.

  http://NeoSmart.net/blog/2008/Windows-Vista-recovery-disc-download/

  ISO Burner: http://www.snapfiles.com/get/active-isoburner.html

  It's a very good Vista startup repair disk.

  You can do a system restart tool, system, etc it restore.

  It is NOT a disc of resettlement.

  And the 32-bit is what normally comes on a computer, unless 64-bit.

• Portege 3440: ntoskrnl.exe file needs to be replaced - how to start without external hard drive

  Hello

  My 3440 has developed a problem, I think the boot.ini file corruption that it requests to the file ntoskrnl.exe replaced at startup. The problem is that I don't have an external drive to boot from. When I press F2 it gives me a list of devices, that which no no it starts from. I don't have the external CD drive for this, and it won't have a USB floppy drive.

  It is impossible for me to solve this problem without the external port replicator or a cd player?

  Thanks in advance

  Pete

  Hello

  Unfortunately, without the access on the Windows CD you will not be able to fix it.

  The ntoskrnl.exe file is placed on the original Windows CD in the i386 folder.
  You could start at the beginning of the CD to make the repair console by pressing R
  In the repair console, you can use this command:

  Expand D:\i386\ntoskrnl.ex_C:\windows\ntoskrnl.exe
  (D is the CD drive)

  But as said above seems that you will need the CD player

  But wait if the i386 folder has been installed on your HARD drive you could expand the ntoskrnl.exe in this folder to C:\windows\

  Windows boot manager cannot start Windows...

  So, fortunately I have a recovery disk and I did a recovery to a previous restore point - and windows came fine. Since then, I have disabled the Windows updates

  The problem is in the power down and turn on the system back in the

  The result is that

  2. I can't get updates

• Qosmio F20-153 - ntoskrnl.exe file missing

  Hello

  I have an almost 5 year old toshiba Qosmio F20-153, which has developed an error with the Windows message root>\system32\ntoskrnl.exe file is missing.
  I wonder if it's fixable without completely re - install the complete operating system that I still have the Toshiba restore disk.

  Any help much appreciated.

  Hey Buddy,

  In my view, your only option is recovering the entire notebook. The Toshiba Recovery disk only contains an image of factory settings, which means that you can t install this single file of this disc.
  In addition it s a good idea to reinstall Windows from time to time. If your installation is already 5 years old, you should do this. You will be surprised with the speed of your laptop is after that. :)

  Use the recovery disk is quite simple: you must boot from that disk and follow the instructions on the screen. You do a few clicks only and that s it!

• Blue screen - ntoskrnl.exe was able to start: kernel missing/corrupted dxgkrnl.sys

  original title: BSOD and freezes, several errors reported, puzzled.

  Hello

  I've been struggling with trying to understand an intermittent problem for the last 3 weeks.  The problem has been around for one more month, but it seems to happen more and more often can't find the source.  I wish I could attach the dump files memory here, but don't see any option for this.  So here it goes...

  Have had this computer for 2-3 years and have not changed the material at all and only the drivers updated.

  CPU: Intel Core i7 CPU * address email is removed from the privacy *.

  Motherboard: ACPI x 64

  PowerSource: Power TX 750W.

  2 Hardrives: WDC - WD6401AALS-00L3B2 ATA

  6 GB OF RAM

  Graphics card: NVIDIA GeForce GTX 260

  I have wiped the two HD, reinstalled Vista.  I've updated the Vista completely.  I've updated the following drivers to their latest: graphics card, motherboard, map its (motherboard), LAN (motherboard).

  The computer crashes more often that the BSOD appears.  When it freezes, the sound plays all that was the last one on again and again and nothing does.  No data memory is dumped to the crash.  I checked with another computer that is on the network to see if she could still access shared files and that he could not.  It has frozen or gave the BSOD when just doing electronic-mail/surf net or playing dungeons and Online (DDO dragons).

  Challenges in a relationship with install/updates: SP2 would not install through normal updating, so a download and install manually.  DDO requires NET framework 1.1 to run.  Had to integrate the installation so that it can install.  Do not remember having to do in the past.  The point of freezing/BSOD is always the same before and after I did the complete wipe.

  Made the following stress tests:

  Don't use memtest 86 + (2.11 and version 4.10) x no errors, 8 longer past track.

  Used Furmark 1.8.2 V max stress test, ran all night without crashing.

  Used Video Card Stability Test (Group in stone), no problem.

  Used Seagate Diagnostics on HD, long and short no trials, no failure.

  Reported on BSOD errors:

  Ntoskrnl.exe could not start: missing/corrupted core

  dxgkrnl.sys

  driver_IRQL_NOT_LESS_OR_EQUAL nvlddmkm.sys

  More information on these if necessary.

  I get about 5 freezes with no info to each BSOD with info.  Very hard to debug with any info.

  I've had freezes/BSOD occur minutes after the computer starts and the hours.  Have the box to open with an external fan blowing into the case.  Don't think overheating is the problem.  No overclocking ever carried out on the system.

  I'm relearning all debugging stuff, did not have to do this in a long time any help would be very appreciated.

  Thanks in advance for your help.

  Hello

  If you do not remove ANY power and reconnect the cables (at both ends, memory and cards)
  When possible) - in fact, remove and replace - do not just tight.

  As you re-installed Vista twice the question must be something that works with a low level
  as the BIOS, chipset of low level drivers or hardware.

  You can validate files minidumps on the SkyDrive or other file sharing sites so that they can be
  downloaded, and we will have a look. But to be honest they will reveal probably material
  or worth nothing useful, so.

  Use SkyDrive download collected files and after shot/screenshot.
