Damaged boot files in Windows XP prevent the operating system from starting in Normal Mode, although you may be able to access Safe Mode. If you are able to enter Safe Mode, try to copy damaged boot files or to modify the boot.ini while in Safe Mode by inserting the Windows XP installation disk and copying files from the disk to your hard drive. If you cannot reach Safe Mode, you will need to initiate repairs through the Windows XP Recovery Console. You will need to know which files you need to replace and their exact file names.
