Fatal Error Solutions
     
 

Check for viruses on your computer. Remove...

STOP: 0x0000007B

 
  Description  
     
 

This issue occurs when Windows has lost access to the boot partition or system partition, typically the C drive on most installations.  This issue can also occur when replacing the motherboard, and re-using the hard drive with the OS already installed.

Some older versions of Windows will show the description as "INACCESSIBLE_BOOT_DEVICE". 

This is a fatal Windows error, typically called a Stop message, Bug Check, or more commonly the Blue Screen of Death (BSoD). The system is in a forced reboot state. Any unsaved work is likely lost.

Use Last Known Good Configuration
8
    Add    Flag
solution icon

If you are unable successfully boot into Windows because of the fatal error, Windows has an option to reload registry information from the last successful boot. To revert to the last successful boot:

  1. Reboot the computer.
  2. Near the end of the BIOS messages or graphic, but well before anything appears from Windows, press the F8 key. You may only have a few seconds to get the right spot to press F8 before it attempts to go into Windows. If the BIOS complains about a pressed key or asks you to go into BIOS setup, you've pressed F8 too soon (Don't go into BIOS setup).
  3. When successful, you should see a black screen with white text "Windows Advanced Options". Use the up or down arrow keys to highlight Last Known Good Configuration and press Enter.

Microsoft has issued a hot fix (a special update) to fix this issue:

When using a USB CD-ROM drive to boot Windows, a bug in Windows can cause this problem. See Microsoft article 839210.

If you uninstalled or installed Roxio Easy CD Creator 5 Platinum Edition, a bug in Easy CD can leave a registry entry pointing to a driver that is no longer installed. For instructions on how to fix this, see Microsoft article 811408.

Fix SATA BIOS Change
7
    Add    Flag
solution icon

If the BIOS disk setting was changed from using Serial Advanced Technology Attachment (SATA) mode of the boot drive to using the Advanced Host Controller Interface (AHCI) specification, this problem will occur. See Microsoft article 922976.

On a Dell E6410 when the BIOS setting is SATA this BSOD occurs.  Changing the BIOS setting to AHCI fixes the problem.  This is exactly opposite of the prior instructions!

Check Hard Disk and Cables
7
    Add    Flag
solution icon

If you had changed, added or removed hard drives, or changed or removed drive cabling, likely something is wrong. Recheck that the drives are properly installed and the cabling has not changed. Switching cables to different motherboard connectors or changing the master/slave drive jumpers (on old ATA drives) can cause this problem. In some systems, the cables were not plugged into the drive or motherboard securely and may have worked loose. Reseat all drive connectors.

It's also possible a hard drive is failing. Use a system diagnostic to validate the drive or swap to another hard disk.

Several software products that offer disk diagnostics includes Fix-It Utilities Professional and SystemSuite Professional. Other diagnostic products include Eurosoft's PC Check and Iolo's System Mechanic.

Perform Registry Cleaning
7
    Add    Flag
solution icon

Fix any registry problems. Use a registry fixer tool to accomplish this. A good registry fixer will fix or remove bad entries and orphaned entries left over from a badly behaving uninstall.

One registry fixer tool that stands out in competitive reviews is part of Fix-It Utilities Professional and SystemSuite Professional.

In this case, the specific concern is the portion of the registry that controls the loading of drivers may be corrupted.

Run Startup Repair (Windows 7/Vista)
7
    Add    Flag
solution icon

If you replaced the motherboard, and kept the existing hard drive with Windows already loaded, perform a Startup Repair.

Windows 7/Vista/2008 offer a semi-automatic way to fix a range of startup and file problems.

  1. Boot from your bootable Windows installation DVD and go into the 7/Vista Recovery Console.
  2. At the System Recovery Options menu, select Startup Repair.
  3. Remove the DVD and select the Restart button.

With luck this will correct the problem.

Partition Table Corrections
6
    Add    Flag
solution icon

You may have a virus or malware that has corrupted the partition table. This table at the start of the first hard drive tells the BIOS (and the OS) how to boot up. Most Anti-virus products cannot fix this error once it occurs.

One product we know of, Partition Commander, has the ability to rebuild a damaged partition table and may be able to fix the issue.

Once working, be sure to do an extensive scan for viruses and malware.

Update the BIOS and BIOS Parameters
6
    Add    Flag
solution icon

Check with the PC manufacturer if you're using the latest BIOS or not. If not, update to the current version.

A few of the manufacture's download or support links for a motherboard/BIOS update:

    If the BIOS is current, it's possible bad BIOS parameters are causing the problem, especially if the memory or CPU settings are overclocked. The BIOS parameters are stored in CMOS memory. The best way to reset the BIOS parameters is to remove the CMOS battery. To do this:

    1. Unplug the PC, and open the case.
    2. Locate the battery on the motherboard - typically a silver coin cell.
    3. Remove the battery and note if the plus side is up or down, so you can reinstall it later the same way.
    4. Wait at least 1 minute and reinstall the battery.
    5. Attach power and power up. Typically a BIOS warning message will indicate CMOS was corrupted or changed and it may require you to go into the BIOS setup to set the time and date.
    6. Proceed to boot Windows and see if this fixes the issue.

    Some BIOSes have options to enable/disable caching and/or shadowing. If the options are available, disable caching and shadowing. Most newer (2005+) systems do not have these options. There are many BIOS makers and customized versions of the BIOS, so you may have to enter BIOS setup and look a bit to find these options. Typically you press a key like Esc, Del, F1, or F2 before Windows starts (almost right after you reboot) to enter BIOS setup. Consult your computer manual for details. The setup key can also be found in our BIOS access list.

    Restore From Backup or Image
    5
        Add    Flag
    solution icon
    If you know the hardware is good and you have a current backup or image of the drive, you could reformat the hard drive and start over. This is often the last resort when all else fails, as you will often lose your latest settings and important data. If you have a spare drive, it may be worth it to install the drive in place of the first drive and do a fresh install of Windows. This will help confirm if this is a hardware or software issue (unless the original system drive is the source of the problem).
