Good Day
Just wanted to share my new experience.
If your system fails to run due to an error corresponding to lost HAL.DLL, invalid Boot.ini or any other important system boot files you can repair this by using the XP installation CD. Simply boot from your XP Setup CD and enter the Recovery Console. Then run "attrib -H -R -S" on the C:\Boot.ini file and remove it. Launch "Bootcfg /Rebuild" and then Fixboot
Cheers,
