Let's use the Windows XP CD to repair your Windows XP installation. A Repair Install will replace the system files with the files on the XP CD used for the Repair Install. It will leave your applications and settings intact, but Windows updates will need to be reapplied.
A Windows XP Repair will replace files altered by viruses and malware, but will not repair an virus infection. Be sure tpo scan your system as soon as it is repaired. If you do not have an anti virus, here is a list of free anti virus scans available on the web.
The Windows XP Repair procedure.
Insert the Windows Xp CD-ROM and reboot your computer. When prompted to press any key to boot from CD press a key.
If you do not get that message it means that you have to change your boot sequence in your BIOS. First, Bookmark This Page so you can come back and continue the installation. To go to the boot sequence change page, Click Here.
When the CD loads press ENTER to setup windows XP. DO NOT PRESS R TO REPAIR! Pressing R now would get you to the windows xp repair console.
Accept the agreement with Microsoft.
Now select your windows XP installation and press R to repair.
Enter the Windows XP CD key.
Choose No and Click Next unless your computer is at the office.
Again press Next! We are almost done repairing your computer (only a few more Next buttons!).
Choose No for now. You can do that once windows xp has finished the repair! I am trying to keep that as short as possible.
Congratulations! Microsoft says you are ready to go! Click Next and you are there.
Remember that repairing Windows XP has not removed viruses or other malwares. If you didn't scan for viruses on the last page, I highly recommend you do so now!
For that you need to update and run your anti virus. If you do not have an antivirus Click Here for a list of free scans and antiviruses on the web. Remember that your Windows XP is not repaired until you scan your computer.
Check also the secure and backup page. You might find usefull tools and advices to help you not waist your time like that anymore.
If you got to this page because your computer doesn't load Windows XP, continue to rebuild your boot partition .
If you got to this site because of Windows XP problems, and this could not help you, proceed to the Antivirus page to get a virus scan.
