Obviously sfc /scannow isn't going to go any further.
In order to run the Repair installation for Windows 7 you will need an installation disc.
If you do not have a Windows 7 installation disc you can download a ISO image at the Windows 7 Forums
. These ISO images are legal to download. These images were hosted at the Digital River store which is an official distribution partner of Microsoft. The images are untouched and genuine, the images are absolutely safe to download.
***If you do have the Windows installation disc go to step 1. in the Windows 7 repair installation below.
You will need to burn the ISO image will need to be burned to a DVD, in order to do this I would suggest ImgBurn.
1) To burn a ISO file to a DVD please downlaod ImgBurn
and install it.
2) Insert blank DVD into your CD/DVD drive.
3) Open ImgBurn, and click on Write image file to disc.
4) Click on the Browse for a file icon:
5) Locate the ISO file you want to burn, and click on the Open button.
6) Click on the blue arrow to start burning the bootable DVD.
In order to boot from the this DVD you may need to change the boot order in the BIOS so that the CD/DVD-ROM is the first device and the hdd the second device.
***Windows 7 repair installation steps.
1. Place the installation disc in the tray of the optical drive and restart the computer.
2. You will be prompted to press any key to start the installation, I find the space bar handy.
At this point the setup process will load files, this will take a couple of minutes.
3. You will now need to choose Language to install, Time and currency format, and Keyboard or input method that you'd like to use.
4. Click on the Repair the computer link on the bottom-left of the Install Windows window.
This link will begin the Windows 7 System Recovery Options.
5. System Recovery Options will now search your hard drive(s) for any Windows 7 installations. This will take a few minutes.
No participation is required on your part, wait till it has finished and the next window will open.
6. Choose the Windows 7 installation that you'd like to perform the Startup Repair on, then clinck on Next
7. Click on the Startup Repair link from list of recovery tools in System Recovery Options.
Several other diagnostic and recovery tools are available in the Windows 7 System Recovery Options including System Restore, System Image Recovery, Windows Memory Diagnostic, and Command Prompt.
8. The Startup Repair tool will now search for problems in the system files.
If Startup Repair finds a problem with any system files the tool may suggest a solution of some kind that you need to confirm, or may solve the problem automatically.
9. Startup Repair will now attempt to repair whatever problems it found with system files.
Note: If Startup Repair did not find any problems with system files you won't see this step.
Important: Your computer may or may not restart several times during this repair process. This is normal, you should allow it to continue until you see the Restart your computer to complete the repairs window.
10. Click on Finish, this will restart your computer.
It is possible that the Startup Repair will not be able to fix the problem. If the Starup Repair tool determines this it may automatcially run the the repair after your computer restarts. If it does not automatically run the repair but you're still having problems with Windows 7 repeat these steps to run Startup Repair again manually.
