Windows xp was deleted by accident when adding a new hard drive. I reinstalled windows software but nothing is working. It says the master file is missing. What do I need to do? I had someone look at it and he believes the mother board is bad. Is that easy and inexpensive to replace or do you think it can be trouble shoot?
