    Hello Njan, and welcome to Seven Forums.

    If you are referring to doing a repair install on your Windows 7, then it must be done from within Windows 7 while you have it fully started. You will not be able to do a repair install at boot.

    You may be able to use the tutorial below to help extract and replace any corrupted system files from your Windows 7 installation disc to hopefully fix them all though.

    Extract Files from Windows 7 Installation DVD

    Hope this helps,
    Shawn

    Do you want to run sfc scan from the dvd or do you want to update offline? If scan, heres how to.

    SFC /SCANNOW : Run in Command Prompt at Boot

    If you want to update offline, download SP and post-SP1 updates on another PC connected to the internet, burn them to dvd, then install on this computer.

    If you want to integrate SP1 into the existing win7 dvd, heres how.

    Slipstream Windows 7 SP1 into a Installation DVD or ISO File

    As Brink references, a Repair Install is normally the next step for unfixable system files. It can be done offline from the desktop by running the DVD or extracted or mounted ISO.

    I would use the tutorial to slipstream SP1 into the ISO before running the Repair Install so you don't have to install it afterward since the OS will be reinstalled while all files, programs and settings will remain in place.
