INACCESSIBLE_BOOT_DEVICE
-
Setup has encountered a fatal error that prevents it from continuing.
Contact your product support representative for assistance. The following status will assist them in diagnosing the problem.
(0x4, 0x1, 0, 0)
Setup cannot continue. Power down or reboot your computer now.
You may also receive a "Stop 0x0000007B"
error message during Windows XP Setup when the Setup program restarts
during the installation process. When you receive a Stop error while the
Setup program is running, you receive the second error message. To
troubleshoot this issue, read the following four sections to determine
if any one of the issues applies to you. If none of the issues apply
to you, use the following general troubleshooting steps at the end of
the article.

Boot-Sector Viruses
You may receive a "Stop 0x0000007B" error message if your computer is
infected with a boot-sector virus. If the problem is intermittent and
you can start Windows, check your computer for viruses. If you find a
virus, also check any floppy disks for viruses before you use them
again.

Note You may have to use more than one brand of virus-detection software to detect and remove various viruses.
Important
If your computer has been infected, it may be open to additional forms
of attack. We recommend that you rebuild infected Internet-facing
servers by following the guidelines that are published on the
CERT
Web site. Internet-facing servers are servers that function without a
firewall or other protection. It is also a good idea to rebuild any
other computers that are at risk because of their proximity to infected
computers before you put them back in service.
If a virus has infected your Windows XP-based computer and a
virus-detection program cannot remove the virus and repair the system,
you must repartition and format your hard disk and reinstall Windows XP.

Device Driver IssuesYou may receive a "Stop 0x0000007B" error message in the following scenarios:
- A device driver that the computer boot controller needs is not configured to start during the startup process.
- A device driver that the computer boot controller needs is corrupted.
- Information in the Windows XP registry (information related to how the device drivers load during startup) is corrupted.
Windows XP requires a miniport driver to communicate with the hard disk
controller that is used to start your computer. If Windows XP does not
supply a device driver for your controller or if Windows XP is using a
corrupted or incompatible driver, you must replace the driver with a
valid copy that is compatible with your controller and Windows XP.
During the first phase of the Windows XP installation, Setup displays the following message at the bottom of the screen:
Press F6 if you have to install a third-party SCSI or RAID driver.
Press F6 and then follow the instructions to install a mass-storage
device driver from your Original Equipment Manufacturer (OEM).
For additional information about using F6 to load an OEM device driver
to support, click the following article number to view the article in
the Microsoft Knowledge Base:
General Troubleshooting
If none of the issues that have been described in this article apply to you, use the following general troubleshooting steps:
- If
you receive one of these error messages while you are installing
Windows XP, update the computer BIOS or obtain Windows XP drivers for
your hard disk controller (from the manufacturer of your computer,
system board, or hard disk controller), or do both. For information
about how to update your computer's BIOS or obtain Windows XP drivers,
contact your computer manufacturer. For additional information about the
availability of drivers, see the Device Driver Issues section in this article.
Note: If Windows NT 4.0 or Windows 2000 was installed previously on a mirrored boot partition, see the Other Issues section in this article.
- Use
the Last Known Good Configuration feature. This may resolve the problem
if you recently installed an incompatible device driver for your boot
controller.

feature, click the following article number to view the article in the
