I'm having problems loading Windows XP. It just stops and gives me an error code.

In regards to getting the "irql_not_less_or_equal" BSOD this can be related to several things. You could be having a driver problem or a hardware related problem. To know exactually what your problem is we need to look at the stop code you are getting as well. The link below will show you what number I need to see exactually where your problem is.

Note Since you have gotten Windows 7 to install most likely the issue is driver related. So the thing to look at with your Windows XP CD does it atleast have SP2 as a part of the install. If it does not you may not have all the chip set drivers that the motherboard needs.

Its an hardware error. You have tech support with MS since you bought the new XP try to see if they can tell you what is the hardware its complaining about.

you are most likely getting a BSOD with a stop error code of 0x0000007B which is caused by the Windows XP CD that you are using doesn't have the SATA Hard Drive controller driver needed to recognize and utilize the hard drive. If Lenovo has XP drivers for this model then they should have a SATA driver (roughly 394k) that will need to be loaded FROM A FLOPPY DISKETTE during the boot to XP. (XP Requires the driver to either be slipstreamed into the CD or loaded from a floppy diskette. Trying to load the controller driver USB or a different CD will not work)

Your trying to downgrade this means you have to use vista cd to format the hard driver, and after the laptop restart, load the Xp. Also sometimes this code comes if you donot use the original xp windows.

Thanks for using Fixy

Go to the bios and change the SATA into ATA before installing window xp. You will find this option under hard disk type.

If your computer constantly restarts while you are using it, or if you are trying to shut down the computer after it has stopped unexpectedly, click to clear the Automatically restart check box. If you clear this check box, you receive an error message when the computer stops responding. This error message may describe the cause of the problem. You can also review the system log in Event Viewer to view the critical stop error that occurs when the computer restarts.

1. Click the Start button, right-click My Computer, click Properties, click the Advanced tab, and then click Settings under Startup and Recovery.
2. Under System Failure, view the Automatically restart check box. If the Automatically restart check box is selected, Windows automatically restarts if the computer stops unexpectedly.

Thanks & Regards

Visit this post on microsoft to resolve your problem.Your RAM may be the cause of the error.

Hello,
1. What the motherboard you had been using
2. Whats the HDD

Check that your motherboard supports the higher HDD
Upto 80GB HDD Windows can load the XP with servicepack 1
But after 80GB HDD supports the WIN XP with service pack 2 CD only.  Try to install with the winxp having above sp1.

A stop error occurs when Windows XP Professional stops responding. Stop error messages can be caused by hardware or software malfunctions. The error messages appear on a blue or black background. The following steps, which also appear on the stop error screen, help you find out the cause of a stop error and how to fix the problem. To troubleshoot General Stop Errors: 1. Restart your PC. Unplug each new hardware device, one at a time, to see if this resolves the error. Try to run any hardware diagnostic software supplied by your computer manufacturer. 2. If this is a new installation of hardware or software, contact the manufacturer for any Windows XP Professional updates or drivers you might need. Click Get support, or find information in Windows XP newsgroups (under "Ask for assistance") and then click Get help from Microsoft in the left-hand column. 3. Check the Microsoft Hardware Compatibility List (HCL) to verify that all your hardware and drivers are compatible with Windows XP Professional. 4. If you can start Windows XP Professional, check the System Log in Event Viewer for additional error messages that might help identify the device or driver causing the problem. 5. If you cant start Windows XP Professional, try to start your computer in safe mode, and then remove or disable any newly added programs or drivers. 6. Search the Microsoft Knowledge Base for "Windows XP Professional" and the number associated with the stop error you received. Specific Stop Errors Some stop errors display descriptive messages such as "DATA_BUS_ERROR" that can help you determine the exact solution for the error. This section discusses how to troubleshoot specific stop errors, based on the type of error you receive.
