Setup cannot continue because the version of Windows on your computer is newer than the version on the CD.

1. If you connect directly to the internet without a router or hardware firewall, disconnect from the internet by physically removing the connections cable, removing a wireless card, or any other means of internet connection.
2. After the Repair install is completed, enable the XP firewall or install third party firewall software or router before connecting to the internet.

A Repair Install is not foolproof and should not be considered the cure-all fix for non-boot situations.
The below procedure applies only if you can still boot into Windows.
To prevent loss of data and/or program settings, perform the following before the Repair Install.
Manually delete the Undo_guimode.txt file from the Windows\System32 folder before you perform any of the actions that are listed in the "Symptoms" section of this article. To do this in Windows XP, type the following command at a command prompt:
del /a /f %windir%\system32\undo_guimode.txt
1.From the Start menu, click Run.
2.In the Run dialog box, in the Open text box, type: cmd. Click OK.
3.Delete the undo_guimode.txt file. In the C:\Windows\System32\cmd.exe dialog box, type: del /a /f c:\windows\system32\undo_guimode.txt. Press the ENTER key.

Very important!!
If you still have the ability to access the Windows XP installation, backup all important files not restorable from other sources before attempting any recovery console or other trouble shooting attempts.
Possible Fix by reconfiguring boot.ini using Recovery Console.
1.Boot with XP CD or 6 floppy boot disk set.
2. Press R to load the Recovery Console.
3. Type bootcfg.
4. This should fix any boot.ini errors causing setup not to see the XP OS
install.
5. Try the repair install.

"Reboot, this time taking the immediate R option and if the CD letter is say K: give these commands

copy K:\i386\ntldr C:\
copy K:\i386\ntdetect.com C:\

(two other files needed - just in case)
1. Type: attrib -h -r -s C:\boot.ini del C:\boot.ini
2. Type: BootCfg /Rebuild

which will get rid of any damaged boot.ini, search the disk for systems and make a new one.
