This issue may occur if your computer BIOS does not correctly manage or support the capacity of the hard disk on which you are installing Windows XP.

Make sure that you are using the latest BIOS revision for your computer. Contact the computer manufacturer to inquire about how to obtain and install the latest BIOS update that is available for the computer.

Open your comp, then remove the disk and connect it to annother computer, then backup your data, make sure you have backed up all of your documents. Return the disk to your comp, format disk and install your operating system. Another way is to get Linux find one that can boot without installation ( I have Linux Ubuntu v7.0.4 that can do this), or Hirens boot CD, load "Mini Windows XP" as you can do backup in Windows enviroment, boot up from CD and save your documents to external drive, USB flash disk, or write them on CD, and after backup do installation of operating system.My advice. Get yourself a newer comp, at least Pentium 4 class, because your computer is no longer, as you can see, reliable to work on. Hope I Helped.
