I have a Dell Latitude D600. Last year I had the hard drive and disc drive replaced. Now I get the message to re-install <windows root>\sysem32\ntoskrnl.exe. I can't get my computor to run the windows disc to re-install the software. I have tried starting my computor in "safe mode", that doesn't get me anywhere, I have tried starting my computor to the last know configeration where everything worked, that doesn't work. I have tried pressing the windows key and R to get the computor to run the disc, that doesn't work. How am I supposed to re-install the file? I am really a dummy when it comes to this stuff....... so the easiest explanation would be appreciated. Like "step by step" directions. LOL Thanks so much to anyone who will HELP!!!!
