  1. Lost admin password Use Linux boot disk to reset admin password: “http://home.eunet.no/~pnordahl/ntpasswd/
  2. Try to boot the system into the “Last Known Good Configuration”.
  3. Boot into Safe Mode and try fixing from there first (disable services, or drivers ).
  4. Run CHKDSK /R /P to repair disk errors.
  5. Run Windows Systems Restore if XP boots.
  6. Replace corrupt NTLDR file, From Recovery Console type: COPY E:\i386\NTLDR C:
  7. Run System Restore from cmd prompt, type:  %systemroot%\system32 restore strui.exe
  8. Insert windows XP Disk and try to do a repair install “Bypass the recovery console”.
  9. Recovery Console: run BOOTCFG /Rebuild to repair Boot.ini. (follow the steps below)

  • Add installation to boot list? (Yes/No/All): Type: Y
  • Enter Load Identifier: Type in any description you want that will identify the installation of Windows (e.g., Windows XP SP2)
  • Enter OS Load Options, Type in:   "/fastdetect" and/or "/NoExecute=OptIn" without the quotes

Typical boot.ini looks like this:
