About 3 days ago, I booted up my computer and after the initial Dell startup, I got a message saying that NTLDR is missing, press ctrl alt del to restart. I have looked all over to find a solution to this, but have not yet found one. There were suggestions to people with a similar problem to insert the Windows XP CD and repair the file from the disk, but this did not work for me. It seems as if my CD-Rom drive is not reading the disk right because nothing happens when I insert the disk. As far as I know, my PC is not trying to boot from a non-bootable source. I did a diagnostic of my CD-ROM drive and it was not reading the media from any disk inserted. I do not know how to fix this problem. Can someone please help me?!?!?!
