While repairing Windows XP, it has setup another version of XP on my computer. So on every reboot, I have to select one Windows XP out of the two presented.

Out of two, one is corrupt and not in use. How do I delete it?

This knowledge base article from Microsoft outlines the steps.

  1. Start the Windows operating system that you want to keep.
  2. To determine the Windows folder that you want to keep, click Start, click Run, type %windir%, and then click OK.
  3. In Windows Explorer, find the Windows folder that you want to remove.
  4. Right-click the Windows folder that you want to remove, Delete. Confirm.
  5. Start, right-click My Computer, Properties.
  6. Advanced tab, Startup and Recovery, Settings. The Startup and Recovery dialog box appears.
  7. Under System startup, click Edit to modify the Boot.ini file.
  The Boot.ini file opens in Notepad and looks similar to the following:
  [boot loader]
  [operating systems]
  multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" 
  multi(0)disk(0)rdisk(0)partition(1)\WINDOWS.0="Microsoft Windows XP Home" 
  1. On the File menu in Notepad, click Save As, and then save a backup copy of the Boot.ini file that is named Boot.old. Exit.
  2. In the Startup and Recovery dialog box, under System startup, click Edit to reopen the Boot.ini file.
  3. In the [boot loader] section of the Boot.ini file, identify and then delete the line of text for the Windows operating system that you want to remove.
  4. Save, exit and restart.
