I am using WIN XP professional on Compaq nc 8230 laptop,as soon as i boot my laptop there is this error " ntldr file is missing, press ctrl+atl+del to restart but after every restart the same error message appears,when i try to repair WIN XP from Win XP setup CD,it asks for 'administrator password' which i dont have, so is there anyway that i can access my DOS mode & copy the files needed into WIN XP directory ? Please i need help ASAP in the matter. !!! P.S : My laptop doesnt support USB flash drive boot up .
