Window xp boots again n again - Lenovo 3000 N100 0768 - Pentium Dual Core T2060 1.6 GHz - 15.4in. TFT PC Desktop

First you need:
To enter Recovery Console in Windows XP, you will need to boot from the Windows XP CD.

Watch for a Press any key to boot from CD... message similar to the one shown above.
Press a key to force the computer to boot from the Windows CD. If you do not press a key, your PC will continue to boot to the Windows XP installation that's currently installed on your hard drive. If this happens, just restart and try to boot to the Windows XP CD again.

1. Enter Windows XP Recovery Console. The Recovery Console is an advanced diagnostic mode of Windows XP with special tools that will allow you to restore the boot.ini file.

When you reach the command line (detailed in Step 6 in the link above), type the following command and then press Enter.

bootcfg /rebuild

The bootcfg utility will scan your hard drives for any Windows XP installations and then display the results. Follow the remaining steps to add your Windows XP installation to the boot.ini file.

The first prompt asks Add installation to boot list? (Yes/No/All).

Type Y in response to this question and press Enter.

The next prompt asks you to Enter Load Identifier:.

This is the name of the operating system. For example, type Windows XP Professional or Windows XP Home Edition and press Enter.

The final prompt asks you to Enter OS Load options:.

Type /Fastdetect here and press Enter.

Take out the Windows XP CD, type exit and then press Enter to restart your PC.

Assuming that a missing or corrupt boot.ini file was your only issue, Windows XP should now start normally.

No solution now, Install Windows XP again on first partition, Make sure BOOT.INI, NTLDR, NTDETECT.COM in the same partition in which Windows XP is loaded. Then install WIndows 8.
OR in the current scenario you've to do much technical work using third-party tools.

Local help is wrong. Windows is "crashing" during a "normal" start-up. Reinstalling Windows might fix the problem. Or, it could be "bad" RAM -- remove all-but-one of the RAM sticks, and try again to boot. If it still fails, remove that stick, and insert one of the "removed" sticks, and try again.

Will it boot into "safe mode" ?

I am going to assume that you are using this laptop to access the internet as that's what they do. There are unrepairable security flaws in XP due to age that no anti-virus/defender software can patch. Your lucky it has lasted so long.

Windows XP is a fairly stable and secure operating system, but errors and other problems will occur from time to time. Unfortunately, some of these errors can damage or corrupt important system files and can lead to Windows XP not booting up correctly. You can repair your Windows XP installation using a process known as a "repair install," overwriting the damaged system files with new versions from your Windows XP installation disc. The repair install process takes approximately one hour, though a large portion of this time will not require any input from you.

1,Start your computer and place the Windows XP installation disc in the drive. If the computer is crashing upon attempting to boot, allow it to restart; otherwise, reboot the computer manually.
2.Press a key to boot from the Windows XP CD if prompted to do so when the computer attempts to boot again. If you are not prompted to boot from the CD, restart the computer again and press the indicated key on the initial BIOS screen to access the "Boot Order" or "Boot Sequence" menu. Select the CD or DVD drive containing the Windows XP installation CD, then press a key when prompted to boot from the disc.
3.Press the "Enter" key on the initial Windows XP welcome screen and press "Enter" again to begin setting up Windows XP. Do not press the key indicated to launch the "Recovery Console," as the Windows XP recovery console is not used to repair corrupted XP installations.
4.Accept the user agreement and wait while the setup program scans your hard drive.
5.Press the "R" key when the Windows XP setup program lists the installed version of XP that it detected to begin the repair installation. If you have more than one version of Windows XP installed, make sure that the proper version is listed before pressing "R."
6.Wait while the Windows XP setup program copies files to your hard drive and begins the installation process. The installation will take 45 minutes or longer, depending on the speed of your computer, during which time all of the Windows XP system files will be overwritten.
7.Confirm your user information as well as the date and time settings on your computer, and enter your Windows XP product key when prompted. Allow the operating system to connect to the Microsoft authentication servers to activate itself.
8.Reinstall any hardware drivers and XP Service Packs that you had previously installed, as your copy of Windows XP will have reverted to the basic installation you had when it was first installed.

I hope you find it very helpful.

Hi,

You will need an XP install CD for this and also set the CD/DVD drive as the first boot device.

1. Watch for a Press any key to boot from CD... message similar to the one shown above.
   
   
2. Press a key to force the computer to boot from the Windows CD. If you do not press a key, your PC will continue to boot to the Windows XP installation that's currently installed on your hard drive. If this happens, simply reboot and try to boot to the Windows XP CD again.
3. When the Windows XP Professional/Home Setup screen appears, press R to enter Recovery Console.
4. The Recovery Console is now loading but needs to know which Windows installation to access. Most users only have a single Windows XP installation so the choice is usually clear.
   To the Which Windows installation would you like to log onto question, press 1 and then Enter.
   
5. The Recovery Console now needs to know the administrator password for this Windows XP installation. Unless you are using a PC in a sizable business network, the administrator password is most likely the same password you use to access Windows XP on a daily basis. To the Type the Administrator password request, enter the password and press Enter.
   Note: If you do not have a password or Windows XP normally starts without asking for one, simply press Enter.
   
6. Type fixmbr and then press Enter.
7. The fixmbr utility will write a master boot record to the hard drive that you're currently using to boot into Windows XP. This will repair any corruption or damage that the master boot record may have.
8. Take out the Windows XP CD, type exit and then press Enter to restart your PC.
   Assuming that a corrupt master boot record was your only issue, Windows XP should now start normally.
   

Regards.

I would suggest to Partition your hdd and then try installing Windows XP. Make sure you have a bootable cd of XP.

Did you do an upgrade or new install? Did you check the system requirements first to see if you could upgrade to Vista? This could all play a part in why it does not boot up. I suggest you reinstall windows XP again.
