No booting system

You may be very familiar with the common messages while operating with windows which says that some files are missing.This may sometime cause you to lose your data or lead to abnormal termination of a program which requires the support of that particular windows file.Sometimes these file missing problem can be so severe that you may not be able to boot into windows.Such kind of problems occur when we accidentally delete some of our system files either manually or while the anti virus program on our system shows that the file is infected and on its prompt for what to do next, we will choose to delete the file.Well these problems can be solved if you have got a disc of Windows Xp Service Pack2.
If you are able to boot into windows then from the start select run and then run “cmd”.Then the command prompt window appear and after inserting the disc of Windows Xp ServicePack2 in the drive, in command prompt type “SFC/SCANNOW”.The system will then search and copy the windows missing file.
If the file missing problem is so severe that you are not able to boot into windows then, boot the windows using the Windows Xp disc.Then continue the process for installing a fresh copy of windows.While you advance through the process, the windows displays previously installed windows.From there the installer will ask you to press R to repair the existing windows.Press R and the windows will do the rest for you.
