STOP: 0x00000085


A fatal error occurred during setup.

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.

  Sample Screen  

A problem has been detected and Windows has been shut down to prevent damage to your computer.


If this is the first time you've seen this Stop error screen, restart your computer. If this screen appears again, follow these steps:

Check to make sure any new hardware or software is properly installed. If this is a new installation, ask your hardware or software manufacturer for any Windows updates you might need.

If problems continue, disable or remove any newly installed hardware or software. Disable BIOS memory options such as caching or shadowing. If you need to use Safe Mode to remove or disable components, restart your computer, press F8 to select Advanced Startup Options, and then select Safe Mode.

Confirm the hardware is working correctly using a hardware diagnostic program. If you suspect a specific hardware item, such as memory stick or video card, try replacing it with known good hardware.

Don't overlook the possibility that hardware was not installed correctly, especially anything you installed just prior to the problems starting. Make sure all cards and memory are securely seated in their slots. Verify disk drive cables are properly connected and are not loose.

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

Fix BOOT.INI (XP/2003 Only)
    Add    Flag
solution icon
Insert the installation CD for your Windows and reboot the system. Assuming the BIOS defaults to booting from the media (usually the default) a "Welcome to Setup" screen appears. Press R to load the Recovery Console. To fix the boot configuration file, type bootcfg. This corrects most errors in the BOOT.INI file.

If you understand the BOOT.INI configuration file, you could also go in and manually edit the file.

Check if you are using the latest hardware drivers, especially the chipset and video drivers. Older drivers are a common contributor to BSoD issues.

You can use a product like Driver Genius or Radar Sync to verify you have the latest drivers and help keep all your drivers up-to-date. If you're comfortable with driver installations, you can individually find and install current drivers.

After the Stop code will be 4 hex values: {Parameter 1, Parameter 2, Parameter 3, Parameter 4}.

Parameter 1 specifies type of violation (other Parameters will depend upon the type).

0x00000000 The OEM HAL(Hardware Abstraction Layer) font is not a valid .fon format file, so setup cannot display text.
0x00000001 Could not initialize the video adapter. This may indicate that the disk that contains Vga.sys (or another video driver that is appropriate to the PC) is damaged or that the computer has video hardware that Windows cannot communicate with.
0x00000002 Not enough memory.
0x00000003 Keyboard initialization failed. If Parameter 2=0, then no keyboard is connected to the computer. If Parameter 2=1, the keyboard layout DLL can't be loaded.

In general, this issue may indicate that the disk that contains the keyboard driver (I8042prt.sys or Kbdclass.sys) is damaged or that the PC has keyboard hardware that Windows cannot communicate with. This failure might also mean that the keyboard layout DLL could not be loaded.
0x00000004 Setup could not resolve the ARC device path name of the device that setup was started from. (ARC device path is how a system boot partition is described in the BOOT.INI file. For example: multi(0)disk(0)rdisk(0)partition(1)WINDOWS="Windows XP Professional")
0x00000005 Partitioning sanity check failed. This error indicates a bug in a disk driver.
