How to Repair Corrupted Windows XP

1. Turn off your computer and insert the Windows XP Reinstallation Disk or boot disk into your computer disk holder.
2. Turn your computer on and hold down the F12 key for 'Boot Menu.'
3. Use the arrow keys to move to the disk drive that your Reinstallation or boot disk is in. For example, if you put the disk in your CD-ROM drive, then use the arrow key to highlight 'CD/DVD/CD-RW Drive' and hit the 'Enter' key. This will start the install procedure needed to repair your corrupted copy of Windows XP. Wait until all of the install files are loaded and you see the 'Welcome to Setup' window.
4. Press 'Enter' to set up Windows XP. Press F8 to agree and then Esc for 'Don't Repair.' You are going to repair your corrupted XP using a delete and replace of Windows files only.
5. Select the NTFS (New Technology File System) partition so it is highlighted. Use the arrow keys if needed. Press the 'Enter' key to set up Windows XP on this selected partition. Press 'C' to continue setup on this partition.
6. Make sure 'Leave the current file system intact (no changes)' is highlighted and press 'Enter' to continue. You will see an option that says 'To use the folder and delete the existing Windows installation in it, press L.' This is the option you want so the existing Windows files will be deleted and the same file location will be overwritten with a file that is not corrupted. Press 'L' and Windows will perform the repair for the entire Windows directory.
