Most likely his hard disk is damaged, It's best to reinstall the operating system. If that doesn't work you should go buy a new internal 2.5 inch hard disk and install it. That should solve the problem.
This problem is easy to solve, just have a little patience, you need not buy another pc, or looking for a coach in this area. The problem is as follows: The files needed to boot is missing or damaged, to resolve this you insert the installation CD for windows, normally pc's bring a disk with the installation image to recover in case of system failure, if no, you can find several torrents with the installation image, just burn it onto DVD, if an experienced user does not need to install windows again, simply get a CD that contains several tools to do the job. FILES the boot.
Ini and other files responsible for the boot is easy to recover, you need not think about buying another PC or even think that all is lost. On the contrary'm giving you hope that the pc can still be recovered.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
