Finding the files on the CD and different startup options

My son called me with the news that the computer would do nothing but display an "NTLDR is missing" message. I tried to give him instructions over the phone, like Robert Stack in "Airplane." Got home, realized the problem is serious. Luckily, I found your site on my Blackberry, followed the instructions and...civilization has returned! Thanks you so much. Couple of suggestions: for Dummies (like yours truly) you could explain how to find the appropriate files for copying from the cd drive to the c drive (I just used the search function, but I was thrown at first when I didn't see the files on the menu). Also, the last instruction, the final instruction, the driving of the golden spike instruction, was different on my machine. I had to go system-advanced-start up and recovery. Just a different set of menus, but again, I was worried that I'd get oh-so-close to the goal and fall short. Anyway, the story ends happily thanks to you, and I'm very grateful!
