This article is intended for advanced computer users. If you are not comfortable with advanced troubleshooting, you might want to ask someone for help or contact support. For information about how to do this, visit the following Microsoft Web site:
Note If you are receiving this error on a Windows 7-based computer, see the following article on the Microsoft website:
- STOP: 0x0000007B (parameter1, parameter2, parameter3, parameter4)
- Setup has encountered a fatal error that prevents it from continuing.

(0x4, 0x1, 0, 0)
Setup cannot continue. Power down or reboot your computer now.
Boot-Sector VirusesYou 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.

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.
During the first phase of the Windows XP installation, Setup displays the following message at the bottom of the screen:
Hardware IssuesYou may receive a "Stop 0x0000007B" error message if there is a resource conflict between the boot controller and another controller or between SCSI devices. You may also receive this Stop error message if drive translation is not being performed or if drive translation was changed. To troubleshoot this issue:
- If an IRQ or I/O port address conflict exists between the boot controller and another controller, Windows XP either stops responding (hangs) or displays a "Stop 0x0000007B" error message. If you recently added new hardware, remove the new hardware or reconfigure it so that it does not conflict with the resources of any other installed controllers.
- If you are using a SCSI hard disk, check the SCSI chain for correct termination. Remove any unused SCSI devices or make sure that each SCSI ID is unique.
- Make sure that drive translation is turned on (if it is required) and that it has not been changed. For example, if you recently switched controllers, this issue may occur.For additional information about this issue, click the following article number to view the article in the Microsoft Knowledge Base:314082 You receive a Stop 0x0000007b error after you move the Windows XP system disk to another computer
Other IssuesOther potential causes of a "Stop 0x0000007B" error message include:
- The boot volume is corrupted and cannot be initiated by Windows XP. If the file system is corrupted and if Windows XP cannot initiate the boot volume during the startup process, either move the drive to another computer that is running Windows XP and run the chkdsk command on that drive or try to create a parallel installation of Windows XP on the drive (in a separate folder). The Windows XP Setup program checks the integrity of the volume before it copies files, and it may fix some problems in the process.
- You are installing Windows XP on a mirrored boot partition that was created by Microsoft Windows NT 4.0. Windows XP does not support Windows NT 4.0 Ftdisk volume sets. If you are running Microsoft Windows 2000, you must convert all Ftdisk volume sets to dynamic volumes before you upgrade to Windows XP. If you are running Windows NT 4.0, break any mirrors and back up all the data on the stripe, the RAID5, or the extended volume sets before you upgrade to Windows XP. Ftdisk sets might not be accessible after the upgrade.
General TroubleshootingIf 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.
