    Startup failure, NTDLL.DLL


    Hi community, my first post here!

    My computer won't start. Tried BIOS, System recovery and Startup kit repair already.
    Getting error 0x0 - ntdll.dll missing / corrupted / infected. (via Startup repair)
    Getting STOP 0x0000006B and 0xFFFFFFFFC0000034. (via BSOD)
    Always when booting computer, I do get BSOD and same over again.

    I think this is caused by Win 7 Home Security 2012 virus, read a few posts about similar issues already.
    Because I've spent hours searching about similar issues, found thread to remove that virus already, but I need to get my computer open ;O

    Any help? Computer won't start at all.

    Regards,
    Jamie

    The file itself is available here: Free Download DLL and Support Forum.

    Not sure how you would go about replacing it on your computer though. If you have a second machine you may be able to slave the hard disk - or maybe boot from a disk or another device. The file belongs in the Windows\System32 folder.

    Doing a search on my machine and see there are other versions/copies of the file located under C:\Windows\winsxs\x86 ... folders. Can you boot the machine from bootable CD?

    Mayhapp someone will come along with advice.

    Yea, the one I linked to is a different size than the one on my system. Better to use on of the copies from your own machine I think. If you can boot the computer from disc, look around under the Windows\winsxs folder. I have five copies of the DLL on my Windows 7 Pro machine.

    Good luck,

    Unable to boot from CD-ROM, memory stick runs OK via BIOS CMD.

    First try booting into Safe Mode with Networking to install, update and run a full scan with Malwarebytes. Then once cleaned run SFC -SCANNOW Command and work through these troubleshooting steps.

    If Safe Mode is not working, download, burn to CD or write to flash stick, boot and run a full scan with Microsoft Standalone System Sweeper.

    Once the System is clean if it won't start boot into System Recovery Options via the F8 menu or disk as shown in tutorial, run Startup Repair repeatedly no matter what it reports. Post back results.

    If this fails, try System Restore from Recovery Options list, then if that fails open a Command Line to run SFC -SCANNOW Run in Command Prompt at Boot.

    As a last resort boot free Partition Wizard bootable CD to Explore C to see if your files are intact, make sure C or the 100mb System Reserved partition (preferred) is marked Active, then click on HD to highlight it, from Disk tab select Rebuild MBR, Apply. If Windows 7 doesn't start and you restored Active flag, run Startup Repair 3 Separate Times.

    If these all fail you can copy out your data using your Windows 7 DVD or Repair CD: Copy & Paste - in Windows Recovery Console or Paragon Rescue CD.
    System Repair Disc - Create

    Then run Factory Recovery from its partition or disks you made or order from Tech Support, or find a Windows 7 installation DVD to clean reinstall using Product Key on COA sticker: Clean Reinstalling Windows 7
