NTLDR is missing

NTLDR is missing just means your MBR got messed up or something along those lines and the program that is used to get windows to turn on can't be found. This isn't a big deal. There are several ways to fix this. I believe the most common is to pop in your XP/2000 cd, boot, get to the command line, and do a fix /mbr or something along those lines. i'm heading out right now, so i can't grab yo uthe exact command, but googling or MS's technet site should prove to be very useful. I wouldn't be too worried about this unless you are getting many errors. That could indicate that your harddrive is dying and that it is corrupting files on it (which means you should get those files off that harddrive as soon as possible). but htat's only if you start getting many errors about different files being missing/corrupt. one or two or so shouldn't be thought of as a big deal
