I put together a system for my daughter and grand kids, who live 1,500 miles away, as a family Christmas present. It uses an ECS motherboard, AMD Sempron processor, 512 MB RAM, and a brand new Maxtor 160 GB IDE drive. I installed Windows XP Pro and other application software. I tested it for a week, powering it on and off, downloading some pgms like AVG, loading digital pictures, configuring 4 users, etc., all without any problems whatsoever. It performed flawlessly all week. I shipped it to her via UPS and it arrived in perfect condition. My granddaughter's boyfriend, with a fair amount of computer knowledge, installed the system and when it was powered up it gave a "disk boot failure". He checked all cables and any obvious problems and found no problems. The system gives the same failure every time. Any suggestions as to how to diagnose this problem from long distance or what the problem might be? It will be very difficult for me to re-create the system so I am hoping for a fix that will save the software and settings. I am somewhat concerned about some one there doing a boot repair if it has the high probablility of destroying all software and settings. I have never had to do this so I do not know the procedure or risks. Thanks for any help.
