i have a problem with my desktop..i dont know what happened i just turned it on one day and it said ntldr is missing press any key to continue. i dont have a clue what to do. i know nothing about computers and i need someone who does to talk me simply through the steps. my other problem is that i fear i may have to use the cd that came with the computer to fix it, but i had to make them myself, every so often a message would come up asking me if i wanted to make cds or something similar and i (yes admittedly stupidly) always clicked later. what the hell should i do? it was an expensive machine and theres loads of stuff on there i dont want to lose :-( if you can help id be most grateful!
