I am unable to start up my laptop. I get this error message.."the following file is missing or corrupt. \WINNT\SYSTEM32\CONFIG\SYSTEMced start up file. I do not have the original system disk nor do I have any Dell repair disk. Can anyone tell me what to do or where I can get a disk from Dell or other source? I took it to a computer repair store and they could not fix and said I needed disk from Dell. Thank you.
