Hi rona11!!


%SYSTEMROOT% is a shortcut for "the folder where Windows is
installed", in almost cases is C:\Windows (the default folder).
For example %SYSTEMROOT%\SYSTEM32 would be C:\Windows\System32.


Your problem is caused by missing or corruption of the file autoexec.nt.
You just need to replace it with a good one.

The known solutions are:
- Just copy the file from another Windows XP system which is working
fine on your %SYSTEMROOT%\SYSTEM32 folder. The XP version must be the
same (Pro or Home).
                     
                        ---------------------------

-Use the Repair folder:
1- Open an Explorer window --> On the Explorer window click on Tools
menu --> Folder Options --> Click on the View tab --> check "Display
contents of System Folders" and "Show hidden files and folders" -->
Uncheck "Hide extensions for known file types" and "Hide protected
operating system files" (ignore the warning message) --> click on
"Apply to all folders" --> Accept and close that window and then click
on View menu --> select Details.

2- Open the C:\Windows\repair folder and copy the autoexec.nt file by
right click and Copy on it.

3- Open the C:\Windows\system32 folder and paste the autoexec.nt file
on it (accept the replace of the old file if it is necessary).

                          -----------------------------

copy the files, reboot your computer.
