Try running chkdsk /r.   Start/Run...type chkdsk /r and hit Enter.  Type Y in new screen, hit Enter.  Reboot the system, the command will execute...on completiion, the system will automatically try to boot into Windows.


Alternatively...to run chkdsk /r from the recovery console...just enter the command chkdsk /r, without any additional modifications.


AFAIK, there is no such command as chkdsk /p /r...chkdsk /p is the command for running a read-only command (with no attempted repair), while chkdsk /r is the most complete chkdsk command and attempts to do everything that chkdsk /f does, while also attempting to recover file data which may be in bad sectors.

You can also run sfc /scannow.


The sfc /scannow command scans all protected system files and replaces corrupted and incorrect versions with correct Microsoft versions.

During this scan you may be prompted to insert your installation disc in the DVD/CD drive, if you have this disc you will want to have it available before you start the scan.  If you don't have this disc and are prompted for it you will need to follow the *instructions below for locating the i386 file.

To initiate this scan go to Start> Run and type in sfc /scannow then press enter.

If files are found during this scan which need to be replaced you may be prompted to insert your installation disc, do so at that time.   If it doesn't ask you for the disc this means that it wasn't necessary to replace any files.   In the event the the system asks you for the disc, you must visit Windows Update immediately after the scan is completed (Please note that there won't be any confirmation dialog - the program will just exit without telling you anything).

***Warning, the steps below involve entering the Registry.  If a mistake is made there this can render your computer inoperable.  For this reason I suggest that you first back up the rigistry.***

Backup Your Registry with ERUNT

  • Please use the following link and scroll down to ERUNT and download it.
  • For version with the Installer:
    Use the setup program to install ERUNT on your computer
  • For the zipped version:
    Unzip all the files into a folder of your choice.
Click Erunt.exe to backup your registry to the folder of your choice.

Note: to restore your registry, go to the folder and start ERUNT.exe

*If you do not have this disc you will need to locate a directory on your system which is named i386. You will need to search for this in the registry, to do this type in regedit in the Search programs and files box and then press Enter, you will see a screen similar to the one below.


To find this you will need to navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup

You will see the list of HKEY options, please notice the arrow to the left of the option, when you click on this arrow the menu will expand and you will be able to find the next step “SOFTWARE”, expand the menu on this option and proceed till you reach “Setup”.  Under “Setup” you will need to find “SourcePath”.  The SourcePath probably has an entry pointing to your CD-ROM drive, and that is why it is asking for the XP CD. This needs to be changed it to C:\, to do this double click on SourcePath, a box will open where you will make this change by typing in C:\.

Restart your computer now and try running the scan again.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.
