Cant get in windows, it starts off by telling me the error in title. I cant get in safe mode. I try a system repair with a windows 7 cd and it says cant repair. I can get in command prompt, any suggestions to make system bootable?

    Boot with the installation CD and try a repair installation.  That should only re-install "clean" versions of the files and replace any missing.

    jerryz636--First thing, scan the PC for malware using your antivirus or other antimalware program.  You could also run MalwareBytes.
    If that is the problem and all is well, read no further other than to remove the malware, of course.
    If the PC is clean and this is something recent, run a System Restore.  Do not run System Restore if you found malware since you may only reinstall it.
    Run SFC /SCANNOW from a command prompt.

    jerryz636--If you have any opportunity to backup your personal data, do so.  Then clean install your Windows OS.
