If your computer system could not continue with your Windows XP installation, there could be only 2 possible problems.
First, is the Windows XP Installation CD. It might have a scratched part where the CD or DVD ROM drive could not read the files. In that case, it could not continue to its installation process.
Second, is the bad sector of your hard disk drive. There might be a bad sector in your hard disk drive where the files from the Installation CD could not be stored in that particular part of the hard disk drive.
