When you are upgrading your computer from Microsoft Windows 98 or Microsoft Windows Millennium Edition (Me) to Windows XP, you may receive the following error message:
Stop 0x0000000A irql_not_less_or_equal
This behavior can occur if there is incompatible hardware or an incompatible device driver on your computer.
If you receive this error message, follow these steps to resolve the issue:
1. Restart the computer and see if you receive an option to revert back to a previous operating system. Choose this option if it is displayed. If you do not receive the option to revert to a previous operating system, skip to step 3.
2. When your computer starts Windows 98 or Windows Me, uninstall any antivirus software and boot manager software (such as Roxio GoBack), and then "clean boot" your computer by using the information in one of the following Microsoft Knowledge Base articles:
) How to Perform a Clean Boot in Windows Millennium Edition
) How to Perform Clean-Boot Troubleshooting for Windows 98
After your computer starts in the "clean boot" environment, try to upgrade to Windows XP again. If the upgrade procedure does not work and you receive the same error message, the problem may be a hardware problem.
3. Remove any unnecessary hardware from the computer. Disconnect any Universal Serial Bus (USB) devices and printers, and remove the network adapter, sound card, serial adapters, and so on.
4. If you continue to receive this error message, you may need to flash the BIOS on the computer's motherboard. Refer to the manufacturer of your computer or the Web site for the motherboard for information about how to do this.
If the above does not help then it is time to start replacing hardware until you find the problem. I had a problem with a SATA data cable that caused this error. It could also be a bad hard drive, bad format on the HD, bad memory stick among other problems. You will just have to experiment to find out.
