SP3 setup changed the boot sector and didn't restore it after setup failure.



    After an unsuccesful SP3 installation attempt, my XP Pro system keeps booting into Windows XP Pro Setup and aborts/reboots due to missing setup file.

    Looks like SP3 setup has changed something in the boot sector and failed to restore it after aborting setup.


    System boots into a setup menu which has 2 options,

    1)Windows XP Pro Setup (default selects this after 3 secs.)

    2)Windows XP Pro (normal boot.. system runs normally when I choose this.)


    I managed to reinstall SP3 successfuly but it keeps entering in boot menu and running the XP Setup everytime I reboot.

    I need to manually select 2 to prevent it getting into an endless loop of reboots.


    There was a temporary setup folder on boot drive named $WIN_NT$.BT. I tried deleting it but it didn't work.


    Is there a way to undo the change that SP3 setup done to the boot sector?

  • The changes you need to make are in the hidden system file:




    which you can edit with Notepad.  You might need to turn on the viewing of hidden files first, in control panel "Folder Options", tab "View"
